Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13670, here are decompositions:

  • 37 + 13633 = 13670
  • 43 + 13627 = 13670
  • 73 + 13597 = 13670
  • 79 + 13591 = 13670
  • 103 + 13567 = 13670
  • 157 + 13513 = 13670
  • 193 + 13477 = 13670
  • 229 + 13441 = 13670

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13670 first appears in π at position 72,547 of the decimal expansion (the 72,547ordinal-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.
