Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187304, here are decompositions:

  • 31 + 187273 = 187304
  • 67 + 187237 = 187304
  • 127 + 187177 = 187304
  • 163 + 187141 = 187304
  • 181 + 187123 = 187304
  • 193 + 187111 = 187304
  • 223 + 187081 = 187304
  • 277 + 187027 = 187304

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 187,304 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 187304 first appears in π at position 391,110 of the decimal expansion (the 391,110ordinal-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.
