Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478684, here are decompositions:

5 + 478679 = 478684
47 + 478637 = 478684
53 + 478631 = 478684
113 + 478571 = 478684
191 + 478493 = 478684
233 + 478451 = 478684
251 + 478433 = 478684
257 + 478427 = 478684

Showing the first eight; more decompositions exist.
