Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1296, here are decompositions:

  • 5 + 1291 = 1296
  • 7 + 1289 = 1296
  • 13 + 1283 = 1296
  • 17 + 1279 = 1296
  • 19 + 1277 = 1296
  • 37 + 1259 = 1296
  • 47 + 1249 = 1296
  • 59 + 1237 = 1296

Showing the first eight; more decompositions exist.
