Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30736, here are decompositions:

  • 23 + 30713 = 30736
  • 29 + 30707 = 30736
  • 47 + 30689 = 30736
  • 59 + 30677 = 30736
  • 179 + 30557 = 30736
  • 197 + 30539 = 30736
  • 227 + 30509 = 30736
  • 239 + 30497 = 30736

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30736 first appears in π at position 110,948 of the decimal expansion (the 110,948ordinal-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.
