Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2798, here are decompositions:

  • 7 + 2791 = 2798
  • 31 + 2767 = 2798
  • 67 + 2731 = 2798
  • 79 + 2719 = 2798
  • 109 + 2689 = 2798
  • 127 + 2671 = 2798
  • 139 + 2659 = 2798
  • 151 + 2647 = 2798

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2798 first appears in π at position 9,355 of the decimal expansion (the 9,355ordinal-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.
