Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187264, here are decompositions:

  • 41 + 187223 = 187264
  • 47 + 187217 = 187264
  • 53 + 187211 = 187264
  • 71 + 187193 = 187264
  • 83 + 187181 = 187264
  • 101 + 187163 = 187264
  • 131 + 187133 = 187264
  • 137 + 187127 = 187264

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 187,264 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 187264 first appears in π at position 512,730 of the decimal expansion (the 512,730ordinal-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.
