Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127028, here are decompositions:

  • 61 + 126967 = 127028
  • 67 + 126961 = 127028
  • 79 + 126949 = 127028
  • 271 + 126757 = 127028
  • 277 + 126751 = 127028
  • 337 + 126691 = 127028
  • 397 + 126631 = 127028
  • 487 + 126541 = 127028

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 127,028 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 127028 first appears in π at position 280,475 of the decimal expansion (the 280,475ordinal-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.
