Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13490, here are decompositions:

  • 3 + 13487 = 13490
  • 13 + 13477 = 13490
  • 73 + 13417 = 13490
  • 79 + 13411 = 13490
  • 109 + 13381 = 13490
  • 151 + 13339 = 13490
  • 163 + 13327 = 13490
  • 181 + 13309 = 13490

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13490 first appears in π at position 82,737 of the decimal expansion (the 82,737ordinal-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.
