Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987944, here are decompositions:

  • 3 + 987941 = 987944
  • 31 + 987913 = 987944
  • 151 + 987793 = 987944
  • 313 + 987631 = 987944
  • 337 + 987607 = 987944
  • 421 + 987523 = 987944
  • 487 + 987457 = 987944
  • 631 + 987313 = 987944

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 987,944 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 987944 first appears in π at position 662,418 of the decimal expansion (the 662,418ordinal-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.
