Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039900, here are decompositions:

  • 3 + 1039897 = 1039900
  • 83 + 1039817 = 1039900
  • 101 + 1039799 = 1039900
  • 131 + 1039769 = 1039900
  • 137 + 1039763 = 1039900
  • 167 + 1039733 = 1039900
  • 233 + 1039667 = 1039900
  • 269 + 1039631 = 1039900

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 3, 9900 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 9900-03-01 (DMMYYYY (Euro, single-digit day))
  • 9900-10-03 (MMDYYYY (US, single-digit day))
  • 9900-03-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,039,900 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1039900 first appears in π at position 190,662 of the decimal expansion (the 190,662ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
