Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17822, here are decompositions:

  • 31 + 17791 = 17822
  • 61 + 17761 = 17822
  • 73 + 17749 = 17822
  • 109 + 17713 = 17822
  • 139 + 17683 = 17822
  • 163 + 17659 = 17822
  • 199 + 17623 = 17822
  • 223 + 17599 = 17822

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17822 first appears in π at position 50,379 of the decimal expansion (the 50,379ordinal-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.
