Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47906, here are decompositions:

  • 3 + 47903 = 47906
  • 37 + 47869 = 47906
  • 97 + 47809 = 47906
  • 109 + 47797 = 47906
  • 127 + 47779 = 47906
  • 163 + 47743 = 47906
  • 193 + 47713 = 47906
  • 277 + 47629 = 47906

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47906 first appears in π at position 119,483 of the decimal expansion (the 119,483ordinal-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.
