Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30994, here are decompositions:

  • 11 + 30983 = 30994
  • 17 + 30977 = 30994
  • 23 + 30971 = 30994
  • 53 + 30941 = 30994
  • 83 + 30911 = 30994
  • 101 + 30893 = 30994
  • 113 + 30881 = 30994
  • 191 + 30803 = 30994

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30994 first appears in π at position 160,221 of the decimal expansion (the 160,221ordinal-suffix:st 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.
