Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6610, here are decompositions:

  • 3 + 6607 = 6610
  • 11 + 6599 = 6610
  • 29 + 6581 = 6610
  • 41 + 6569 = 6610
  • 47 + 6563 = 6610
  • 59 + 6551 = 6610
  • 89 + 6521 = 6610
  • 137 + 6473 = 6610

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6610 first appears in π at position 2,747 of the decimal expansion (the 2,747ordinal-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.
