Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39200, here are decompositions:

  • 19 + 39181 = 39200
  • 37 + 39163 = 39200
  • 43 + 39157 = 39200
  • 61 + 39139 = 39200
  • 67 + 39133 = 39200
  • 97 + 39103 = 39200
  • 103 + 39097 = 39200
  • 157 + 39043 = 39200

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39200 first appears in π at position 325,681 of the decimal expansion (the 325,681ordinal-suffix:st 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.
