Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39672, here are decompositions:

  • 5 + 39667 = 39672
  • 13 + 39659 = 39672
  • 41 + 39631 = 39672
  • 53 + 39619 = 39672
  • 103 + 39569 = 39672
  • 109 + 39563 = 39672
  • 131 + 39541 = 39672
  • 151 + 39521 = 39672

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39672 first appears in π at position 145,727 of the decimal expansion (the 145,727ordinal-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.
