Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19746, here are decompositions:

  • 7 + 19739 = 19746
  • 19 + 19727 = 19746
  • 29 + 19717 = 19746
  • 37 + 19709 = 19746
  • 47 + 19699 = 19746
  • 59 + 19687 = 19746
  • 137 + 19609 = 19746
  • 149 + 19597 = 19746

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19746 first appears in π at position 32,869 of the decimal expansion (the 32,869ordinal-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.
