Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522660, here are decompositions:

  • 23 + 522637 = 522660
  • 37 + 522623 = 522660
  • 59 + 522601 = 522660
  • 107 + 522553 = 522660
  • 137 + 522523 = 522660
  • 139 + 522521 = 522660
  • 163 + 522497 = 522660
  • 181 + 522479 = 522660

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 522,660 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 522660 first appears in π at position 94,193 of the decimal expansion (the 94,193ordinal-suffix:rd 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.
