Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61724, here are decompositions:

  • 7 + 61717 = 61724
  • 37 + 61687 = 61724
  • 43 + 61681 = 61724
  • 67 + 61657 = 61724
  • 73 + 61651 = 61724
  • 97 + 61627 = 61724
  • 163 + 61561 = 61724
  • 181 + 61543 = 61724

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61724 first appears in π at position 354,198 of the decimal expansion (the 354,198ordinal-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.
