Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622, here are decompositions:

  • 13 + 8609 = 8622
  • 23 + 8599 = 8622
  • 41 + 8581 = 8622
  • 59 + 8563 = 8622
  • 79 + 8543 = 8622
  • 83 + 8539 = 8622
  • 101 + 8521 = 8622
  • 109 + 8513 = 8622

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8622 first appears in π at position 1,908 of the decimal expansion (the 1,908ordinal-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.
