Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16624, here are decompositions:

  • 5 + 16619 = 16624
  • 17 + 16607 = 16624
  • 71 + 16553 = 16624
  • 131 + 16493 = 16624
  • 137 + 16487 = 16624
  • 173 + 16451 = 16624
  • 191 + 16433 = 16624
  • 197 + 16427 = 16624

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16624 first appears in π at position 37,977 of the decimal expansion (the 37,977ordinal-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.
