Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478828, here are decompositions:

5 + 478823 = 478828
17 + 478811 = 478828
41 + 478787 = 478828
59 + 478769 = 478828
89 + 478739 = 478828
101 + 478727 = 478828
131 + 478697 = 478828
149 + 478679 = 478828

Showing the first eight; more decompositions exist.
