Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20962, here are decompositions:

  • 3 + 20959 = 20962
  • 23 + 20939 = 20962
  • 41 + 20921 = 20962
  • 59 + 20903 = 20962
  • 83 + 20879 = 20962
  • 89 + 20873 = 20962
  • 113 + 20849 = 20962
  • 173 + 20789 = 20962

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20962 first appears in π at position 329 of the decimal expansion (the 329ordinal-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.
