Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38000, here are decompositions:

  • 3 + 37997 = 38000
  • 7 + 37993 = 38000
  • 13 + 37987 = 38000
  • 37 + 37963 = 38000
  • 43 + 37957 = 38000
  • 103 + 37897 = 38000
  • 139 + 37861 = 38000
  • 283 + 37717 = 38000

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38000 first appears in π at position 1,596 of the decimal expansion (the 1,596ordinal-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.
