Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987950, here are decompositions:

  • 37 + 987913 = 987950
  • 157 + 987793 = 987950
  • 211 + 987739 = 987950
  • 409 + 987541 = 987950
  • 487 + 987463 = 987950
  • 739 + 987211 = 987950
  • 751 + 987199 = 987950
  • 757 + 987193 = 987950

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 987,950 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 987950 first appears in π at position 142,674 of the decimal expansion (the 142,674ordinal-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.
