Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85900, here are decompositions:

  • 11 + 85889 = 85900
  • 47 + 85853 = 85900
  • 53 + 85847 = 85900
  • 71 + 85829 = 85900
  • 83 + 85817 = 85900
  • 107 + 85793 = 85900
  • 149 + 85751 = 85900
  • 167 + 85733 = 85900

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85900 first appears in π at position 18,499 of the decimal expansion (the 18,499ordinal-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.
