Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85658, here are decompositions:

  • 19 + 85639 = 85658
  • 31 + 85627 = 85658
  • 37 + 85621 = 85658
  • 61 + 85597 = 85658
  • 109 + 85549 = 85658
  • 127 + 85531 = 85658
  • 211 + 85447 = 85658
  • 229 + 85429 = 85658

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85658 first appears in π at position 67,171 of the decimal expansion (the 67,171ordinal-suffix:st 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.
