Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520824, here are decompositions:

  • 11 + 520813 = 520824
  • 37 + 520787 = 520824
  • 61 + 520763 = 520824
  • 103 + 520721 = 520824
  • 107 + 520717 = 520824
  • 191 + 520633 = 520824
  • 193 + 520631 = 520824
  • 257 + 520567 = 520824

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 520,824 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 520824 first appears in π at position 345,839 of the decimal expansion (the 345,839ordinal-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.
