Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16600, here are decompositions:

  • 47 + 16553 = 16600
  • 53 + 16547 = 16600
  • 71 + 16529 = 16600
  • 107 + 16493 = 16600
  • 113 + 16487 = 16600
  • 149 + 16451 = 16600
  • 167 + 16433 = 16600
  • 173 + 16427 = 16600

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16600 first appears in π at position 106,785 of the decimal expansion (the 106,785ordinal-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.
