Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186308, here are decompositions:

  • 7 + 186301 = 186308
  • 37 + 186271 = 186308
  • 61 + 186247 = 186308
  • 79 + 186229 = 186308
  • 97 + 186211 = 186308
  • 151 + 186157 = 186308
  • 211 + 186097 = 186308
  • 271 + 186037 = 186308

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 186,308 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 186308 first appears in π at position 444,543 of the decimal expansion (the 444,543ordinal-suffix:rd 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.
