Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19748, here are decompositions:

  • 31 + 19717 = 19748
  • 61 + 19687 = 19748
  • 67 + 19681 = 19748
  • 139 + 19609 = 19748
  • 151 + 19597 = 19748
  • 241 + 19507 = 19748
  • 271 + 19477 = 19748
  • 277 + 19471 = 19748

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19748 first appears in π at position 8,650 of the decimal expansion (the 8,650ordinal-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.
