Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85810, here are decompositions:

  • 17 + 85793 = 85810
  • 29 + 85781 = 85810
  • 59 + 85751 = 85810
  • 107 + 85703 = 85810
  • 149 + 85661 = 85810
  • 167 + 85643 = 85810
  • 191 + 85619 = 85810
  • 233 + 85577 = 85810

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85810 first appears in π at position 36,210 of the decimal expansion (the 36,210ordinal-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.
