Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522730, here are decompositions:

  • 11 + 522719 = 522730
  • 23 + 522707 = 522730
  • 41 + 522689 = 522730
  • 53 + 522677 = 522730
  • 71 + 522659 = 522730
  • 107 + 522623 = 522730
  • 233 + 522497 = 522730
  • 251 + 522479 = 522730

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 522,730 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 522730 first appears in π at position 539,195 of the decimal expansion (the 539,195ordinal-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.
