Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126926, here are decompositions:

  • 3 + 126923 = 126926
  • 13 + 126913 = 126926
  • 67 + 126859 = 126926
  • 103 + 126823 = 126926
  • 193 + 126733 = 126926
  • 223 + 126703 = 126926
  • 313 + 126613 = 126926
  • 379 + 126547 = 126926

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 126,926 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 126926 first appears in π at position 144,787 of the decimal expansion (the 144,787ordinal-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.
