Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981004, here are decompositions:

  • 5 + 980999 = 981004
  • 41 + 980963 = 981004
  • 47 + 980957 = 981004
  • 83 + 980921 = 981004
  • 107 + 980897 = 981004
  • 173 + 980831 = 981004
  • 293 + 980711 = 981004
  • 317 + 980687 = 981004

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 981,004 and was likely granted around 1910.

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

Position in π

The digit sequence 981004 first appears in π at position 688,627 of the decimal expansion (the 688,627ordinal-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.
