Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521022, here are decompositions:

  • 13 + 521009 = 521022
  • 41 + 520981 = 521022
  • 53 + 520969 = 521022
  • 59 + 520963 = 521022
  • 79 + 520943 = 521022
  • 101 + 520921 = 521022
  • 109 + 520913 = 521022
  • 181 + 520841 = 521022

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 521,022 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 521022 first appears in π at position 191,619 of the decimal expansion (the 191,619ordinal-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.
