Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19682, here are decompositions:

  • 73 + 19609 = 19682
  • 79 + 19603 = 19682
  • 139 + 19543 = 19682
  • 151 + 19531 = 19682
  • 181 + 19501 = 19682
  • 193 + 19489 = 19682
  • 199 + 19483 = 19682
  • 211 + 19471 = 19682

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19682 first appears in π at position 11,756 of the decimal expansion (the 11,756ordinal-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.
