Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127258, here are decompositions:

  • 11 + 127247 = 127258
  • 17 + 127241 = 127258
  • 41 + 127217 = 127258
  • 101 + 127157 = 127258
  • 179 + 127079 = 127258
  • 227 + 127031 = 127258
  • 269 + 126989 = 127258
  • 401 + 126857 = 127258

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 127,258 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 127258 first appears in π at position 24,736 of the decimal expansion (the 24,736ordinal-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.
