Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187168, here are decompositions:

  • 5 + 187163 = 187168
  • 29 + 187139 = 187168
  • 41 + 187127 = 187168
  • 101 + 187067 = 187168
  • 251 + 186917 = 187168
  • 461 + 186707 = 187168
  • 467 + 186701 = 187168
  • 479 + 186689 = 187168

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 187,168 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 187168 first appears in π at position 834,246 of the decimal expansion (the 834,246ordinal-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.
