Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472728, here are decompositions:

7 + 472721 = 472728
17 + 472711 = 472728
19 + 472709 = 472728
31 + 472697 = 472728
37 + 472691 = 472728
41 + 472687 = 472728
59 + 472669 = 472728
89 + 472639 = 472728

Showing the first eight; more decompositions exist.
