Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478630, here are decompositions:

3 + 478627 = 478630
41 + 478589 = 478630
59 + 478571 = 478630
107 + 478523 = 478630
137 + 478493 = 478630
149 + 478481 = 478630
179 + 478451 = 478630
197 + 478433 = 478630

Showing the first eight; more decompositions exist.
