Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13682, here are decompositions:

  • 3 + 13679 = 13682
  • 13 + 13669 = 13682
  • 241 + 13441 = 13682
  • 271 + 13411 = 13682
  • 283 + 13399 = 13682
  • 373 + 13309 = 13682
  • 433 + 13249 = 13682
  • 463 + 13219 = 13682

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13682 first appears in π at position 37,829 of the decimal expansion (the 37,829ordinal-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.
