Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121426, here are decompositions:

  • 5 + 121421 = 121426
  • 23 + 121403 = 121426
  • 47 + 121379 = 121426
  • 59 + 121367 = 121426
  • 83 + 121343 = 121426
  • 113 + 121313 = 121426
  • 167 + 121259 = 121426
  • 197 + 121229 = 121426

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 121,426 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 121426 first appears in π at position 403,699 of the decimal expansion (the 403,699ordinal-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.
