Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72226, here are decompositions:

  • 3 + 72223 = 72226
  • 5 + 72221 = 72226
  • 53 + 72173 = 72226
  • 59 + 72167 = 72226
  • 137 + 72089 = 72226
  • 149 + 72077 = 72226
  • 173 + 72053 = 72226
  • 179 + 72047 = 72226

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72226 first appears in π at position 111,859 of the decimal expansion (the 111,859ordinal-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.
