Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121126, here are decompositions:

  • 3 + 121123 = 121126
  • 59 + 121067 = 121126
  • 107 + 121019 = 121126
  • 113 + 121013 = 121126
  • 149 + 120977 = 121126
  • 179 + 120947 = 121126
  • 197 + 120929 = 121126
  • 227 + 120899 = 121126

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 121,126 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 121126 first appears in π at position 862,858 of the decimal expansion (the 862,858ordinal-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.
