Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13570, here are decompositions:

  • 3 + 13567 = 13570
  • 17 + 13553 = 13570
  • 47 + 13523 = 13570
  • 71 + 13499 = 13570
  • 83 + 13487 = 13570
  • 101 + 13469 = 13570
  • 107 + 13463 = 13570
  • 113 + 13457 = 13570

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13570 first appears in π at position 97,360 of the decimal expansion (the 97,360ordinal-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.
