Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126338, here are decompositions:

  • 31 + 126307 = 126338
  • 67 + 126271 = 126338
  • 97 + 126241 = 126338
  • 109 + 126229 = 126338
  • 127 + 126211 = 126338
  • 139 + 126199 = 126338
  • 211 + 126127 = 126338
  • 241 + 126097 = 126338

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 126,338 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 126338 first appears in π at position 270,667 of the decimal expansion (the 270,667ordinal-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.
