Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30664, here are decompositions:

  • 3 + 30661 = 30664
  • 71 + 30593 = 30664
  • 107 + 30557 = 30664
  • 167 + 30497 = 30664
  • 173 + 30491 = 30664
  • 197 + 30467 = 30664
  • 233 + 30431 = 30664
  • 317 + 30347 = 30664

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30664 first appears in π at position 115 of the decimal expansion (the 115ordinal-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.
