Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012900, here are decompositions:

  • 71 + 1012829 = 1012900
  • 89 + 1012811 = 1012900
  • 131 + 1012769 = 1012900
  • 137 + 1012763 = 1012900
  • 149 + 1012751 = 1012900
  • 167 + 1012733 = 1012900
  • 179 + 1012721 = 1012900
  • 197 + 1012703 = 1012900

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 2900 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2900-10-01 (MMDYYYY (US, single-digit day))
  • 2900-01-10 (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 1,012,900 and was likely granted around 1911.

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

Position in π

The digit sequence 1012900 first appears in π at position 476,070 of the decimal expansion (the 476,070ordinal-suffix:th 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.
