Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91288, here are decompositions:

  • 5 + 91283 = 91288
  • 59 + 91229 = 91288
  • 89 + 91199 = 91288
  • 137 + 91151 = 91288
  • 149 + 91139 = 91288
  • 167 + 91121 = 91288
  • 191 + 91097 = 91288
  • 269 + 91019 = 91288

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 91288 first appears in π at position 41,200 of the decimal expansion (the 41,200ordinal-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.
