Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16626, here are decompositions:

  • 7 + 16619 = 16626
  • 19 + 16607 = 16626
  • 23 + 16603 = 16626
  • 53 + 16573 = 16626
  • 59 + 16567 = 16626
  • 73 + 16553 = 16626
  • 79 + 16547 = 16626
  • 97 + 16529 = 16626

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16626 first appears in π at position 68,547 of the decimal expansion (the 68,547ordinal-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.
