Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556890, here are decompositions:

  • 7 + 556883 = 556890
  • 23 + 556867 = 556890
  • 29 + 556861 = 556890
  • 31 + 556859 = 556890
  • 41 + 556849 = 556890
  • 67 + 556823 = 556890
  • 71 + 556819 = 556890
  • 73 + 556817 = 556890

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 556,890 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 556890 first appears in π at position 353,215 of the decimal expansion (the 353,215ordinal-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.
