Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472818, here are decompositions:

  • 19 + 472799 = 472818
  • 67 + 472751 = 472818
  • 97 + 472721 = 472818
  • 107 + 472711 = 472818
  • 109 + 472709 = 472818
  • 127 + 472691 = 472818
  • 131 + 472687 = 472818
  • 149 + 472669 = 472818

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 472,818 and was likely granted around 1891.

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

Position in π

The digit sequence 472818 first appears in π at position 143,582 of the decimal expansion (the 143,582ordinal-suffix:nd 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.
