Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1330, here are decompositions:

  • 3 + 1327 = 1330
  • 11 + 1319 = 1330
  • 23 + 1307 = 1330
  • 29 + 1301 = 1330
  • 41 + 1289 = 1330
  • 47 + 1283 = 1330
  • 53 + 1277 = 1330
  • 71 + 1259 = 1330

Showing the first eight; more decompositions exist.
