Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24960, here are decompositions:

  • 7 + 24953 = 24960
  • 17 + 24943 = 24960
  • 37 + 24923 = 24960
  • 41 + 24919 = 24960
  • 43 + 24917 = 24960
  • 53 + 24907 = 24960
  • 71 + 24889 = 24960
  • 83 + 24877 = 24960

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24960 first appears in π at position 8,958 of the decimal expansion (the 8,958ordinal-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.
