Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85906, here are decompositions:

  • 3 + 85903 = 85906
  • 17 + 85889 = 85906
  • 53 + 85853 = 85906
  • 59 + 85847 = 85906
  • 89 + 85817 = 85906
  • 113 + 85793 = 85906
  • 173 + 85733 = 85906
  • 239 + 85667 = 85906

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85906 first appears in π at position 177,781 of the decimal expansion (the 177,781ordinal-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.
