Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040870, here are decompositions:

  • 13 + 1040857 = 1040870
  • 37 + 1040833 = 1040870
  • 43 + 1040827 = 1040870
  • 67 + 1040803 = 1040870
  • 73 + 1040797 = 1040870
  • 139 + 1040731 = 1040870
  • 199 + 1040671 = 1040870
  • 211 + 1040659 = 1040870

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 0870 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0870-04-01 (DMMYYYY (Euro, single-digit day))
  • 0870-10-04 (MMDYYYY (US, single-digit day))
  • 0870-04-10 (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 1,040,870 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 1040870 first appears in π at position 78,298 of the decimal expansion (the 78,298ordinal-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.
