Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2982, here are decompositions:

  • 11 + 2971 = 2982
  • 13 + 2969 = 2982
  • 19 + 2963 = 2982
  • 29 + 2953 = 2982
  • 43 + 2939 = 2982
  • 73 + 2909 = 2982
  • 79 + 2903 = 2982
  • 103 + 2879 = 2982

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2982 first appears in π at position 33,130 of the decimal expansion (the 33,130ordinal-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.
