Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24986, here are decompositions:

  • 7 + 24979 = 24986
  • 19 + 24967 = 24986
  • 43 + 24943 = 24986
  • 67 + 24919 = 24986
  • 79 + 24907 = 24986
  • 97 + 24889 = 24986
  • 109 + 24877 = 24986
  • 127 + 24859 = 24986

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24986 first appears in π at position 22,959 of the decimal expansion (the 22,959ordinal-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.
