Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47170, here are decompositions:

  • 23 + 47147 = 47170
  • 41 + 47129 = 47170
  • 47 + 47123 = 47170
  • 59 + 47111 = 47170
  • 83 + 47087 = 47170
  • 113 + 47057 = 47170
  • 173 + 46997 = 47170
  • 251 + 46919 = 47170

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47170 first appears in π at position 104,852 of the decimal expansion (the 104,852ordinal-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.
