Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20914, here are decompositions:

  • 11 + 20903 = 20914
  • 17 + 20897 = 20914
  • 41 + 20873 = 20914
  • 107 + 20807 = 20914
  • 167 + 20747 = 20914
  • 197 + 20717 = 20914
  • 233 + 20681 = 20914
  • 251 + 20663 = 20914

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20914 first appears in π at position 3,472 of the decimal expansion (the 3,472ordinal-suffix:nd 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.
