Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1424, here are decompositions:

  • 43 + 1381 = 1424
  • 97 + 1327 = 1424
  • 103 + 1321 = 1424
  • 127 + 1297 = 1424
  • 193 + 1231 = 1424
  • 211 + 1213 = 1424
  • 223 + 1201 = 1424
  • 271 + 1153 = 1424

Showing the first eight; more decompositions exist.
