Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47866, here are decompositions:

  • 23 + 47843 = 47866
  • 29 + 47837 = 47866
  • 47 + 47819 = 47866
  • 59 + 47807 = 47866
  • 89 + 47777 = 47866
  • 149 + 47717 = 47866
  • 167 + 47699 = 47866
  • 227 + 47639 = 47866

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47866 first appears in π at position 200,610 of the decimal expansion (the 200,610ordinal-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.
