Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3136, here are decompositions:

  • 17 + 3119 = 3136
  • 47 + 3089 = 3136
  • 53 + 3083 = 3136
  • 113 + 3023 = 3136
  • 137 + 2999 = 3136
  • 167 + 2969 = 3136
  • 173 + 2963 = 3136
  • 179 + 2957 = 3136

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 3136 first appears in π at position 1,303 of the decimal expansion (the 1,303ordinal-suffix:rd 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.
