Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188066, here are decompositions:

  • 37 + 188029 = 188066
  • 79 + 187987 = 188066
  • 103 + 187963 = 188066
  • 139 + 187927 = 188066
  • 157 + 187909 = 188066
  • 223 + 187843 = 188066
  • 367 + 187699 = 188066
  • 379 + 187687 = 188066

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 188,066 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 188066 first appears in π at position 53,700 of the decimal expansion (the 53,700ordinal-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.
