Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187192, here are decompositions:

  • 3 + 187189 = 187192
  • 11 + 187181 = 187192
  • 29 + 187163 = 187192
  • 53 + 187139 = 187192
  • 59 + 187133 = 187192
  • 101 + 187091 = 187192
  • 149 + 187043 = 187192
  • 233 + 186959 = 187192

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 187,192 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 187192 first appears in π at position 719,858 of the decimal expansion (the 719,858ordinal-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.
