Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126560, here are decompositions:

  • 13 + 126547 = 126560
  • 19 + 126541 = 126560
  • 43 + 126517 = 126560
  • 61 + 126499 = 126560
  • 67 + 126493 = 126560
  • 73 + 126487 = 126560
  • 79 + 126481 = 126560
  • 103 + 126457 = 126560

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 126,560 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 126560 first appears in π at position 114,340 of the decimal expansion (the 114,340ordinal-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.
