Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556900, here are decompositions:

  • 17 + 556883 = 556900
  • 41 + 556859 = 556900
  • 59 + 556841 = 556900
  • 83 + 556817 = 556900
  • 89 + 556811 = 556900
  • 101 + 556799 = 556900
  • 107 + 556793 = 556900
  • 131 + 556769 = 556900

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 556,900 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 556900 first appears in π at position 15,815 of the decimal expansion (the 15,815ordinal-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.
