Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47530, here are decompositions:

  • 3 + 47527 = 47530
  • 17 + 47513 = 47530
  • 23 + 47507 = 47530
  • 29 + 47501 = 47530
  • 71 + 47459 = 47530
  • 89 + 47441 = 47530
  • 113 + 47417 = 47530
  • 149 + 47381 = 47530

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47530 first appears in π at position 80,923 of the decimal expansion (the 80,923ordinal-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.
