Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47864, here are decompositions:

  • 7 + 47857 = 47864
  • 67 + 47797 = 47864
  • 73 + 47791 = 47864
  • 127 + 47737 = 47864
  • 151 + 47713 = 47864
  • 163 + 47701 = 47864
  • 211 + 47653 = 47864
  • 241 + 47623 = 47864

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47864 first appears in π at position 150,687 of the decimal expansion (the 150,687ordinal-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.
