Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478786, here are decompositions:

17 + 478769 = 478786
23 + 478763 = 478786
47 + 478739 = 478786
59 + 478727 = 478786
89 + 478697 = 478786
107 + 478679 = 478786
149 + 478637 = 478786
197 + 478589 = 478786

Showing the first eight; more decompositions exist.
