Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8556, here are decompositions:

  • 13 + 8543 = 8556
  • 17 + 8539 = 8556
  • 19 + 8537 = 8556
  • 29 + 8527 = 8556
  • 43 + 8513 = 8556
  • 89 + 8467 = 8556
  • 109 + 8447 = 8556
  • 113 + 8443 = 8556

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8556 first appears in π at position 1,724 of the decimal expansion (the 1,724ordinal-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.
