Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24520, here are decompositions:

  • 3 + 24517 = 24520
  • 11 + 24509 = 24520
  • 47 + 24473 = 24520
  • 101 + 24419 = 24520
  • 107 + 24413 = 24520
  • 113 + 24407 = 24520
  • 149 + 24371 = 24520
  • 191 + 24329 = 24520

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24520 first appears in π at position 15,720 of the decimal expansion (the 15,720ordinal-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.
