Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478470, here are decompositions:

11 + 478459 = 478470
17 + 478453 = 478470
19 + 478451 = 478470
29 + 478441 = 478470
37 + 478433 = 478470
43 + 478427 = 478470
53 + 478417 = 478470
59 + 478411 = 478470

Showing the first eight; more decompositions exist.
