Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30974, here are decompositions:

  • 3 + 30971 = 30974
  • 37 + 30937 = 30974
  • 43 + 30931 = 30974
  • 103 + 30871 = 30974
  • 157 + 30817 = 30974
  • 193 + 30781 = 30974
  • 211 + 30763 = 30974
  • 271 + 30703 = 30974

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30974 first appears in π at position 136,303 of the decimal expansion (the 136,303ordinal-suffix:rd 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.
