Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31022, here are decompositions:

  • 3 + 31019 = 31022
  • 73 + 30949 = 31022
  • 151 + 30871 = 31022
  • 163 + 30859 = 31022
  • 181 + 30841 = 31022
  • 193 + 30829 = 31022
  • 241 + 30781 = 31022
  • 373 + 30649 = 31022

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31022 first appears in π at position 243,768 of the decimal expansion (the 243,768ordinal-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.
