Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24480, here are decompositions:

  • 7 + 24473 = 24480
  • 11 + 24469 = 24480
  • 37 + 24443 = 24480
  • 41 + 24439 = 24480
  • 59 + 24421 = 24480
  • 61 + 24419 = 24480
  • 67 + 24413 = 24480
  • 73 + 24407 = 24480

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24480 first appears in π at position 33,638 of the decimal expansion (the 33,638ordinal-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.
