Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6684, here are decompositions:

  • 5 + 6679 = 6684
  • 11 + 6673 = 6684
  • 23 + 6661 = 6684
  • 31 + 6653 = 6684
  • 47 + 6637 = 6684
  • 103 + 6581 = 6684
  • 107 + 6577 = 6684
  • 113 + 6571 = 6684

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6684 first appears in π at position 1,287 of the decimal expansion (the 1,287ordinal-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.
