Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13508, here are decompositions:

  • 31 + 13477 = 13508
  • 67 + 13441 = 13508
  • 97 + 13411 = 13508
  • 109 + 13399 = 13508
  • 127 + 13381 = 13508
  • 181 + 13327 = 13508
  • 199 + 13309 = 13508
  • 211 + 13297 = 13508

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13508 first appears in π at position 95,019 of the decimal expansion (the 95,019ordinal-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.
