Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30566, here are decompositions:

  • 7 + 30559 = 30566
  • 13 + 30553 = 30566
  • 37 + 30529 = 30566
  • 73 + 30493 = 30566
  • 97 + 30469 = 30566
  • 139 + 30427 = 30566
  • 163 + 30403 = 30566
  • 199 + 30367 = 30566

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30566 first appears in π at position 105,798 of the decimal expansion (the 105,798ordinal-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.
