Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187874, here are decompositions:

  • 3 + 187871 = 187874
  • 13 + 187861 = 187874
  • 31 + 187843 = 187874
  • 163 + 187711 = 187874
  • 223 + 187651 = 187874
  • 241 + 187633 = 187874
  • 277 + 187597 = 187874
  • 367 + 187507 = 187874

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 187,874 and was likely granted around 1875.

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

Position in π

The digit sequence 187874 first appears in π at position 38,473 of the decimal expansion (the 38,473ordinal-suffix:rd 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.
