Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91166, here are decompositions:

  • 3 + 91163 = 91166
  • 7 + 91159 = 91166
  • 13 + 91153 = 91166
  • 37 + 91129 = 91166
  • 67 + 91099 = 91166
  • 157 + 91009 = 91166
  • 373 + 90793 = 91166
  • 379 + 90787 = 91166

Showing the first eight; more decompositions exist.
