Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478818, here are decompositions:

5 + 478813 = 478818
7 + 478811 = 478818
17 + 478801 = 478818
31 + 478787 = 478818
71 + 478747 = 478818
79 + 478739 = 478818
89 + 478729 = 478818
107 + 478711 = 478818

Showing the first eight; more decompositions exist.
