Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187080, here are decompositions:

  • 7 + 187073 = 187080
  • 11 + 187069 = 187080
  • 13 + 187067 = 187080
  • 31 + 187049 = 187080
  • 37 + 187043 = 187080
  • 53 + 187027 = 187080
  • 71 + 187009 = 187080
  • 163 + 186917 = 187080

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 187,080 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 187080 first appears in π at position 995,220 of the decimal expansion (the 995,220ordinal-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.
