Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520572, here are decompositions:

  • 5 + 520567 = 520572
  • 23 + 520549 = 520572
  • 43 + 520529 = 520572
  • 139 + 520433 = 520572
  • 149 + 520423 = 520572
  • 163 + 520409 = 520572
  • 179 + 520393 = 520572
  • 191 + 520381 = 520572

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 520,572 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 520572 first appears in π at position 209,489 of the decimal expansion (the 209,489ordinal-suffix:th 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.
