Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24660, here are decompositions:

  • 29 + 24631 = 24660
  • 37 + 24623 = 24660
  • 67 + 24593 = 24660
  • 89 + 24571 = 24660
  • 109 + 24551 = 24660
  • 113 + 24547 = 24660
  • 127 + 24533 = 24660
  • 151 + 24509 = 24660

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24660 first appears in π at position 45,732 of the decimal expansion (the 45,732ordinal-suffix:nd 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.
