Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13340, here are decompositions:

  • 3 + 13337 = 13340
  • 13 + 13327 = 13340
  • 31 + 13309 = 13340
  • 43 + 13297 = 13340
  • 73 + 13267 = 13340
  • 157 + 13183 = 13340
  • 163 + 13177 = 13340
  • 181 + 13159 = 13340

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13340 first appears in π at position 78,717 of the decimal expansion (the 78,717ordinal-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.
