Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12650, here are decompositions:

  • 3 + 12647 = 12650
  • 13 + 12637 = 12650
  • 31 + 12619 = 12650
  • 37 + 12613 = 12650
  • 61 + 12589 = 12650
  • 67 + 12583 = 12650
  • 73 + 12577 = 12650
  • 97 + 12553 = 12650

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12650 first appears in π at position 32,364 of the decimal expansion (the 32,364ordinal-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.
