Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478490, here are decompositions:

7 + 478483 = 478490
31 + 478459 = 478490
37 + 478453 = 478490
73 + 478417 = 478490
79 + 478411 = 478490
139 + 478351 = 478490
151 + 478339 = 478490
277 + 478213 = 478490

Showing the first eight; more decompositions exist.
