Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91290, here are decompositions:

  • 7 + 91283 = 91290
  • 37 + 91253 = 91290
  • 41 + 91249 = 91290
  • 47 + 91243 = 91290
  • 53 + 91237 = 91290
  • 61 + 91229 = 91290
  • 97 + 91193 = 91290
  • 107 + 91183 = 91290

Showing the first eight; more decompositions exist.
