Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178262, here are decompositions:

  • 3 + 178259 = 178262
  • 13 + 178249 = 178262
  • 31 + 178231 = 178262
  • 79 + 178183 = 178262
  • 193 + 178069 = 178262
  • 223 + 178039 = 178262
  • 241 + 178021 = 178262
  • 283 + 177979 = 178262

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 178,262 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 178262 first appears in π at position 595,451 of the decimal expansion (the 595,451ordinal-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.
