Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1210, here are decompositions:

  • 17 + 1193 = 1210
  • 23 + 1187 = 1210
  • 29 + 1181 = 1210
  • 47 + 1163 = 1210
  • 59 + 1151 = 1210
  • 101 + 1109 = 1210
  • 107 + 1103 = 1210
  • 113 + 1097 = 1210

Showing the first eight; more decompositions exist.
