Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36816, here are decompositions:

  • 7 + 36809 = 36816
  • 23 + 36793 = 36816
  • 29 + 36787 = 36816
  • 37 + 36779 = 36816
  • 67 + 36749 = 36816
  • 103 + 36713 = 36816
  • 107 + 36709 = 36816
  • 139 + 36677 = 36816

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 36816 first appears in π at position 60,022 of the decimal expansion (the 60,022ordinal-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.
