Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39828, here are decompositions:

  • 7 + 39821 = 39828
  • 29 + 39799 = 39828
  • 37 + 39791 = 39828
  • 59 + 39769 = 39828
  • 67 + 39761 = 39828
  • 79 + 39749 = 39828
  • 101 + 39727 = 39828
  • 109 + 39719 = 39828

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39828 first appears in π at position 98,813 of the decimal expansion (the 98,813ordinal-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.
