Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2824, here are decompositions:

  • 5 + 2819 = 2824
  • 23 + 2801 = 2824
  • 47 + 2777 = 2824
  • 71 + 2753 = 2824
  • 83 + 2741 = 2824
  • 113 + 2711 = 2824
  • 131 + 2693 = 2824
  • 137 + 2687 = 2824

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2824 first appears in π at position 8,858 of the decimal expansion (the 8,858ordinal-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.
