Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125278, here are decompositions:

  • 17 + 125261 = 125278
  • 47 + 125231 = 125278
  • 59 + 125219 = 125278
  • 71 + 125207 = 125278
  • 137 + 125141 = 125278
  • 359 + 124919 = 125278
  • 431 + 124847 = 125278
  • 479 + 124799 = 125278

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 125,278 and was likely granted around 1871.

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

Position in π

The digit sequence 125278 first appears in π at position 137,802 of the decimal expansion (the 137,802ordinal-suffix:nd 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.
