Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478776, here are decompositions:

7 + 478769 = 478776
13 + 478763 = 478776
29 + 478747 = 478776
37 + 478739 = 478776
47 + 478729 = 478776
79 + 478697 = 478776
97 + 478679 = 478776
139 + 478637 = 478776

Showing the first eight; more decompositions exist.
