Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91066, here are decompositions:

  • 47 + 91019 = 91066
  • 89 + 90977 = 91066
  • 149 + 90917 = 91066
  • 179 + 90887 = 91066
  • 233 + 90833 = 91066
  • 263 + 90803 = 91066
  • 317 + 90749 = 91066
  • 389 + 90677 = 91066

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 91066 first appears in π at position 42,061 of the decimal expansion (the 42,061ordinal-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.
