Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30824, here are decompositions:

  • 7 + 30817 = 30824
  • 43 + 30781 = 30824
  • 61 + 30763 = 30824
  • 67 + 30757 = 30824
  • 97 + 30727 = 30824
  • 127 + 30697 = 30824
  • 163 + 30661 = 30824
  • 181 + 30643 = 30824

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30824 first appears in π at position 267,749 of the decimal expansion (the 267,749ordinal-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.
