Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91210, here are decompositions:

  • 11 + 91199 = 91210
  • 17 + 91193 = 91210
  • 47 + 91163 = 91210
  • 59 + 91151 = 91210
  • 71 + 91139 = 91210
  • 83 + 91127 = 91210
  • 89 + 91121 = 91210
  • 113 + 91097 = 91210

Showing the first eight; more decompositions exist.
