Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127946, here are decompositions:

  • 73 + 127873 = 127946
  • 79 + 127867 = 127946
  • 97 + 127849 = 127946
  • 103 + 127843 = 127946
  • 109 + 127837 = 127946
  • 127 + 127819 = 127946
  • 139 + 127807 = 127946
  • 199 + 127747 = 127946

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 127,946 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 127946 first appears in π at position 341,508 of the decimal expansion (the 341,508ordinal-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.
