Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470724, here are decompositions:

  • 5 + 470719 = 470724
  • 13 + 470711 = 470724
  • 61 + 470663 = 470724
  • 71 + 470653 = 470724
  • 73 + 470651 = 470724
  • 97 + 470627 = 470724
  • 103 + 470621 = 470724
  • 127 + 470597 = 470724

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 470,724 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 470724 first appears in π at position 907,532 of the decimal expansion (the 907,532ordinal-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.
