Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51118, here are decompositions:

  • 47 + 51071 = 51118
  • 59 + 51059 = 51118
  • 71 + 51047 = 51118
  • 149 + 50969 = 51118
  • 167 + 50951 = 51118
  • 227 + 50891 = 51118
  • 251 + 50867 = 51118
  • 269 + 50849 = 51118

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51118 first appears in π at position 81,082 of the decimal expansion (the 81,082ordinal-suffix:nd 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.
