Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38970, here are decompositions:

  • 11 + 38959 = 38970
  • 17 + 38953 = 38970
  • 37 + 38933 = 38970
  • 47 + 38923 = 38970
  • 53 + 38917 = 38970
  • 67 + 38903 = 38970
  • 79 + 38891 = 38970
  • 97 + 38873 = 38970

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38970 first appears in π at position 128,278 of the decimal expansion (the 128,278ordinal-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.
