Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2918, here are decompositions:

  • 31 + 2887 = 2918
  • 61 + 2857 = 2918
  • 67 + 2851 = 2918
  • 127 + 2791 = 2918
  • 151 + 2767 = 2918
  • 199 + 2719 = 2918
  • 211 + 2707 = 2918
  • 229 + 2689 = 2918

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2918 first appears in π at position 44,516 of the decimal expansion (the 44,516ordinal-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.
