Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512722, here are decompositions:

  • 5 + 512717 = 512722
  • 11 + 512711 = 512722
  • 59 + 512663 = 512722
  • 101 + 512621 = 512722
  • 113 + 512609 = 512722
  • 131 + 512591 = 512722
  • 149 + 512573 = 512722
  • 179 + 512543 = 512722

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 512,722 and was likely granted around 1893.

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

Position in π

The digit sequence 512722 first appears in π at position 290,163 of the decimal expansion (the 290,163ordinal-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.
