Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82212, here are decompositions:

  • 5 + 82207 = 82212
  • 19 + 82193 = 82212
  • 23 + 82189 = 82212
  • 29 + 82183 = 82212
  • 41 + 82171 = 82212
  • 59 + 82153 = 82212
  • 71 + 82141 = 82212
  • 73 + 82139 = 82212

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82212 first appears in π at position 63,230 of the decimal expansion (the 63,230ordinal-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.
