Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478768, here are decompositions:

5 + 478763 = 478768
29 + 478739 = 478768
41 + 478727 = 478768
71 + 478697 = 478768
89 + 478679 = 478768
131 + 478637 = 478768
137 + 478631 = 478768
179 + 478589 = 478768

Showing the first eight; more decompositions exist.
