Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30954, here are decompositions:

  • 5 + 30949 = 30954
  • 13 + 30941 = 30954
  • 17 + 30937 = 30954
  • 23 + 30931 = 30954
  • 43 + 30911 = 30954
  • 61 + 30893 = 30954
  • 73 + 30881 = 30954
  • 83 + 30871 = 30954

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30954 first appears in π at position 23,675 of the decimal expansion (the 23,675ordinal-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.
