Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8528, here are decompositions:

  • 7 + 8521 = 8528
  • 61 + 8467 = 8528
  • 67 + 8461 = 8528
  • 97 + 8431 = 8528
  • 109 + 8419 = 8528
  • 139 + 8389 = 8528
  • 151 + 8377 = 8528
  • 199 + 8329 = 8528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8528 first appears in π at position 6,826 of the decimal expansion (the 6,826ordinal-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.
