Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126758, here are decompositions:

  • 7 + 126751 = 126758
  • 19 + 126739 = 126758
  • 67 + 126691 = 126758
  • 127 + 126631 = 126758
  • 157 + 126601 = 126758
  • 211 + 126547 = 126758
  • 241 + 126517 = 126758
  • 271 + 126487 = 126758

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 126,758 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 126758 first appears in π at position 137,669 of the decimal expansion (the 137,669ordinal-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.
