Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127418, here are decompositions:

  • 19 + 127399 = 127418
  • 97 + 127321 = 127418
  • 127 + 127291 = 127418
  • 157 + 127261 = 127418
  • 199 + 127219 = 127418
  • 211 + 127207 = 127418
  • 229 + 127189 = 127418
  • 337 + 127081 = 127418

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 127,418 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 127418 first appears in π at position 447,204 of the decimal expansion (the 447,204ordinal-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.
