Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39730, here are decompositions:

  • 3 + 39727 = 39730
  • 11 + 39719 = 39730
  • 59 + 39671 = 39730
  • 71 + 39659 = 39730
  • 107 + 39623 = 39730
  • 149 + 39581 = 39730
  • 167 + 39563 = 39730
  • 179 + 39551 = 39730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39730 first appears in π at position 48,422 of the decimal expansion (the 48,422ordinal-suffix:nd 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.
