Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1480, here are decompositions:

  • 29 + 1451 = 1480
  • 41 + 1439 = 1480
  • 47 + 1433 = 1480
  • 53 + 1427 = 1480
  • 71 + 1409 = 1480
  • 107 + 1373 = 1480
  • 113 + 1367 = 1480
  • 173 + 1307 = 1480

Showing the first eight; more decompositions exist.
