Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47730, here are decompositions:

  • 13 + 47717 = 47730
  • 17 + 47713 = 47730
  • 19 + 47711 = 47730
  • 29 + 47701 = 47730
  • 31 + 47699 = 47730
  • 71 + 47659 = 47730
  • 73 + 47657 = 47730
  • 101 + 47629 = 47730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47730 first appears in π at position 29,634 of the decimal expansion (the 29,634ordinal-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.
