Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24440, here are decompositions:

  • 19 + 24421 = 24440
  • 61 + 24379 = 24440
  • 67 + 24373 = 24440
  • 103 + 24337 = 24440
  • 193 + 24247 = 24440
  • 211 + 24229 = 24440
  • 271 + 24169 = 24440
  • 307 + 24133 = 24440

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24440 first appears in π at position 45,135 of the decimal expansion (the 45,135ordinal-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.
