Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3646, here are decompositions:

  • 3 + 3643 = 3646
  • 23 + 3623 = 3646
  • 29 + 3617 = 3646
  • 53 + 3593 = 3646
  • 89 + 3557 = 3646
  • 107 + 3539 = 3646
  • 113 + 3533 = 3646
  • 179 + 3467 = 3646

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3646 first appears in π at position 11,487 of the decimal expansion (the 11,487ordinal-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.
