Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2992, here are decompositions:

  • 23 + 2969 = 2992
  • 29 + 2963 = 2992
  • 53 + 2939 = 2992
  • 83 + 2909 = 2992
  • 89 + 2903 = 2992
  • 113 + 2879 = 2992
  • 131 + 2861 = 2992
  • 149 + 2843 = 2992

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2992 first appears in π at position 47,039 of the decimal expansion (the 47,039ordinal-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.
