Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472780, here are decompositions:

17 + 472763 = 472780
29 + 472751 = 472780
59 + 472721 = 472780
71 + 472709 = 472780
83 + 472697 = 472780
89 + 472691 = 472780
137 + 472643 = 472780
149 + 472631 = 472780

Showing the first eight; more decompositions exist.
