Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520722, here are decompositions:

  • 5 + 520717 = 520722
  • 19 + 520703 = 520722
  • 23 + 520699 = 520722
  • 31 + 520691 = 520722
  • 43 + 520679 = 520722
  • 73 + 520649 = 520722
  • 89 + 520633 = 520722
  • 101 + 520621 = 520722

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 520,722 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 520722 first appears in π at position 107,906 of the decimal expansion (the 107,906ordinal-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.
