Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478690, here are decompositions:

11 + 478679 = 478690
53 + 478637 = 478690
59 + 478631 = 478690
101 + 478589 = 478690
167 + 478523 = 478690
197 + 478493 = 478690
239 + 478451 = 478690
257 + 478433 = 478690

Showing the first eight; more decompositions exist.
