Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9930, here are decompositions:

  • 7 + 9923 = 9930
  • 23 + 9907 = 9930
  • 29 + 9901 = 9930
  • 43 + 9887 = 9930
  • 47 + 9883 = 9930
  • 59 + 9871 = 9930
  • 71 + 9859 = 9930
  • 73 + 9857 = 9930

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 9930 first appears in π at position 24,540 of the decimal expansion (the 24,540ordinal-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.
