Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987650, here are decompositions:

  • 19 + 987631 = 987650
  • 43 + 987607 = 987650
  • 109 + 987541 = 987650
  • 127 + 987523 = 987650
  • 193 + 987457 = 987650
  • 337 + 987313 = 987650
  • 439 + 987211 = 987650
  • 457 + 987193 = 987650

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 987,650 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 987650 first appears in π at position 305,795 of the decimal expansion (the 305,795ordinal-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.
