Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8568, here are decompositions:

  • 5 + 8563 = 8568
  • 29 + 8539 = 8568
  • 31 + 8537 = 8568
  • 41 + 8527 = 8568
  • 47 + 8521 = 8568
  • 67 + 8501 = 8568
  • 101 + 8467 = 8568
  • 107 + 8461 = 8568

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8568 first appears in π at position 6,720 of the decimal expansion (the 6,720ordinal-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.
