Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478662, here are decompositions:

11 + 478651 = 478662
31 + 478631 = 478662
59 + 478603 = 478662
73 + 478589 = 478662
83 + 478579 = 478662
89 + 478573 = 478662
131 + 478531 = 478662
139 + 478523 = 478662

Showing the first eight; more decompositions exist.
