Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85806, here are decompositions:

  • 13 + 85793 = 85806
  • 73 + 85733 = 85806
  • 89 + 85717 = 85806
  • 103 + 85703 = 85806
  • 137 + 85669 = 85806
  • 139 + 85667 = 85806
  • 163 + 85643 = 85806
  • 167 + 85639 = 85806

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85806 first appears in π at position 229,640 of the decimal expansion (the 229,640ordinal-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.
