Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24240, here are decompositions:

  • 11 + 24229 = 24240
  • 17 + 24223 = 24240
  • 37 + 24203 = 24240
  • 43 + 24197 = 24240
  • 59 + 24181 = 24240
  • 61 + 24179 = 24240
  • 71 + 24169 = 24240
  • 89 + 24151 = 24240

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24240 first appears in π at position 31,797 of the decimal expansion (the 31,797ordinal-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.
