Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20762, here are decompositions:

  • 3 + 20759 = 20762
  • 13 + 20749 = 20762
  • 19 + 20743 = 20762
  • 31 + 20731 = 20762
  • 43 + 20719 = 20762
  • 151 + 20611 = 20762
  • 163 + 20599 = 20762
  • 199 + 20563 = 20762

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20762 first appears in π at position 13,989 of the decimal expansion (the 13,989ordinal-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.
