Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556880, here are decompositions:

  • 13 + 556867 = 556880
  • 19 + 556861 = 556880
  • 31 + 556849 = 556880
  • 61 + 556819 = 556880
  • 127 + 556753 = 556880
  • 139 + 556741 = 556880
  • 157 + 556723 = 556880
  • 193 + 556687 = 556880

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 556,880 and was likely granted around 1895.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 556880 first appears in π at position 577,030 of the decimal expansion (the 577,030ordinal-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.
