Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13560, here are decompositions:

  • 7 + 13553 = 13560
  • 23 + 13537 = 13560
  • 37 + 13523 = 13560
  • 47 + 13513 = 13560
  • 61 + 13499 = 13560
  • 73 + 13487 = 13560
  • 83 + 13477 = 13560
  • 97 + 13463 = 13560

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13560 first appears in π at position 96,096 of the decimal expansion (the 96,096ordinal-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.
