Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187344, here are decompositions:

  • 5 + 187339 = 187344
  • 7 + 187337 = 187344
  • 41 + 187303 = 187344
  • 67 + 187277 = 187344
  • 71 + 187273 = 187344
  • 107 + 187237 = 187344
  • 127 + 187217 = 187344
  • 151 + 187193 = 187344

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 187,344 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 187344 first appears in π at position 213,935 of the decimal expansion (the 213,935ordinal-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.
