Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38972, here are decompositions:

  • 13 + 38959 = 38972
  • 19 + 38953 = 38972
  • 139 + 38833 = 38972
  • 151 + 38821 = 38972
  • 181 + 38791 = 38972
  • 223 + 38749 = 38972
  • 379 + 38593 = 38972
  • 523 + 38449 = 38972

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38972 first appears in π at position 50,634 of the decimal expansion (the 50,634ordinal-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.
