Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47580, here are decompositions:

  • 11 + 47569 = 47580
  • 17 + 47563 = 47580
  • 37 + 47543 = 47580
  • 47 + 47533 = 47580
  • 53 + 47527 = 47580
  • 59 + 47521 = 47580
  • 67 + 47513 = 47580
  • 73 + 47507 = 47580

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 47580 first appears in π at position 21,151 of the decimal expansion (the 21,151ordinal-suffix:st 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.
