Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5122, here are decompositions:

  • 3 + 5119 = 5122
  • 23 + 5099 = 5122
  • 41 + 5081 = 5122
  • 71 + 5051 = 5122
  • 83 + 5039 = 5122
  • 101 + 5021 = 5122
  • 113 + 5009 = 5122
  • 149 + 4973 = 5122

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 5122 first appears in π at position 5,181 of the decimal expansion (the 5,181ordinal-suffix:st 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.
