Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127298, here are decompositions:

  • 7 + 127291 = 127298
  • 37 + 127261 = 127298
  • 79 + 127219 = 127298
  • 109 + 127189 = 127298
  • 331 + 126967 = 127298
  • 337 + 126961 = 127298
  • 349 + 126949 = 127298
  • 439 + 126859 = 127298

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 127,298 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 127298 first appears in π at position 208,481 of the decimal expansion (the 208,481ordinal-suffix:st 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.
