Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125218, here are decompositions:

  • 11 + 125207 = 125218
  • 17 + 125201 = 125218
  • 101 + 125117 = 125218
  • 227 + 124991 = 125218
  • 239 + 124979 = 125218
  • 311 + 124907 = 125218
  • 419 + 124799 = 125218
  • 449 + 124769 = 125218

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 125,218 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 125218 first appears in π at position 74,282 of the decimal expansion (the 74,282ordinal-suffix:nd 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.
