Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1270, here are decompositions:

  • 11 + 1259 = 1270
  • 41 + 1229 = 1270
  • 47 + 1223 = 1270
  • 53 + 1217 = 1270
  • 83 + 1187 = 1270
  • 89 + 1181 = 1270
  • 107 + 1163 = 1270
  • 167 + 1103 = 1270

Showing the first eight; more decompositions exist.
