Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556830, here are decompositions:

  • 7 + 556823 = 556830
  • 11 + 556819 = 556830
  • 13 + 556817 = 556830
  • 19 + 556811 = 556830
  • 31 + 556799 = 556830
  • 37 + 556793 = 556830
  • 41 + 556789 = 556830
  • 61 + 556769 = 556830

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 556,830 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 556830 first appears in π at position 172,133 of the decimal expansion (the 172,133ordinal-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.
