Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6654, here are decompositions:

  • 17 + 6637 = 6654
  • 47 + 6607 = 6654
  • 73 + 6581 = 6654
  • 83 + 6571 = 6654
  • 101 + 6553 = 6654
  • 103 + 6551 = 6654
  • 107 + 6547 = 6654
  • 163 + 6491 = 6654

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 6654 first appears in π at position 1,528 of the decimal expansion (the 1,528ordinal-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.
