Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478728, here are decompositions:

17 + 478711 = 478728
31 + 478697 = 478728
97 + 478631 = 478728
101 + 478627 = 478728
139 + 478589 = 478728
149 + 478579 = 478728
157 + 478571 = 478728
197 + 478531 = 478728

Showing the first eight; more decompositions exist.
