Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5866, here are decompositions:

  • 5 + 5861 = 5866
  • 17 + 5849 = 5866
  • 23 + 5843 = 5866
  • 53 + 5813 = 5866
  • 59 + 5807 = 5866
  • 83 + 5783 = 5866
  • 149 + 5717 = 5866
  • 173 + 5693 = 5866

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 5866 first appears in π at position 22,525 of the decimal expansion (the 22,525ordinal-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.
