Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127616, here are decompositions:

  • 7 + 127609 = 127616
  • 19 + 127597 = 127616
  • 37 + 127579 = 127616
  • 67 + 127549 = 127616
  • 109 + 127507 = 127616
  • 163 + 127453 = 127616
  • 193 + 127423 = 127616
  • 367 + 127249 = 127616

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 127,616 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 127616 first appears in π at position 776,733 of the decimal expansion (the 776,733ordinal-suffix:rd 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.
