Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51122, here are decompositions:

  • 13 + 51109 = 51122
  • 61 + 51061 = 51122
  • 79 + 51043 = 51122
  • 151 + 50971 = 51122
  • 193 + 50929 = 51122
  • 199 + 50923 = 51122
  • 229 + 50893 = 51122
  • 283 + 50839 = 51122

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51122 first appears in π at position 61,968 of the decimal expansion (the 61,968ordinal-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.
