Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478770, here are decompositions:

7 + 478763 = 478770
23 + 478747 = 478770
29 + 478741 = 478770
31 + 478739 = 478770
41 + 478729 = 478770
43 + 478727 = 478770
59 + 478711 = 478770
73 + 478697 = 478770

Showing the first eight; more decompositions exist.
