Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520724, here are decompositions:

  • 3 + 520721 = 520724
  • 7 + 520717 = 520724
  • 103 + 520621 = 520724
  • 157 + 520567 = 520724
  • 277 + 520447 = 520724
  • 313 + 520411 = 520724
  • 331 + 520393 = 520724
  • 367 + 520357 = 520724

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 520,724 and was likely granted around 1894.

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

Position in π

The digit sequence 520724 first appears in π at position 907,131 of the decimal expansion (the 907,131ordinal-suffix:st 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.
