Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188250, here are decompositions:

  • 53 + 188197 = 188250
  • 61 + 188189 = 188250
  • 71 + 188179 = 188250
  • 79 + 188171 = 188250
  • 103 + 188147 = 188250
  • 107 + 188143 = 188250
  • 113 + 188137 = 188250
  • 229 + 188021 = 188250

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 188,250 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 188250 first appears in π at position 871,471 of the decimal expansion (the 871,471ordinal-suffix:st 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.
