Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122726, here are decompositions:

  • 7 + 122719 = 122726
  • 73 + 122653 = 122726
  • 127 + 122599 = 122726
  • 193 + 122533 = 122726
  • 199 + 122527 = 122726
  • 223 + 122503 = 122726
  • 229 + 122497 = 122726
  • 277 + 122449 = 122726

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 122,726 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 122726 first appears in π at position 918,970 of the decimal expansion (the 918,970ordinal-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.
