Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19626, here are decompositions:

  • 17 + 19609 = 19626
  • 23 + 19603 = 19626
  • 29 + 19597 = 19626
  • 43 + 19583 = 19626
  • 67 + 19559 = 19626
  • 73 + 19553 = 19626
  • 83 + 19543 = 19626
  • 137 + 19489 = 19626

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19626 first appears in π at position 37,382 of the decimal expansion (the 37,382ordinal-suffix:nd 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.
