Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007900, here are decompositions:

  • 13 + 1007887 = 1007900
  • 43 + 1007857 = 1007900
  • 73 + 1007827 = 1007900
  • 151 + 1007749 = 1007900
  • 181 + 1007719 = 1007900
  • 199 + 1007701 = 1007900
  • 373 + 1007527 = 1007900
  • 433 + 1007467 = 1007900

Showing the first eight; more decompositions exist.

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 1,007,900 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 1007900 first appears in π at position 509,813 of the decimal expansion (the 509,813ordinal-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.
