Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127766, here are decompositions:

  • 3 + 127763 = 127766
  • 19 + 127747 = 127766
  • 97 + 127669 = 127766
  • 103 + 127663 = 127766
  • 109 + 127657 = 127766
  • 157 + 127609 = 127766
  • 313 + 127453 = 127766
  • 367 + 127399 = 127766

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 127,766 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 127766 first appears in π at position 656,804 of the decimal expansion (the 656,804ordinal-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.
