Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72970, here are decompositions:

  • 11 + 72959 = 72970
  • 17 + 72953 = 72970
  • 47 + 72923 = 72970
  • 59 + 72911 = 72970
  • 101 + 72869 = 72970
  • 173 + 72797 = 72970
  • 251 + 72719 = 72970
  • 263 + 72707 = 72970

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72970 first appears in π at position 15,730 of the decimal expansion (the 15,730ordinal-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.
