Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478430, here are decompositions:

3 + 478427 = 478430
13 + 478417 = 478430
19 + 478411 = 478430
31 + 478399 = 478430
79 + 478351 = 478430
109 + 478321 = 478430
157 + 478273 = 478430
223 + 478207 = 478430

Showing the first eight; more decompositions exist.
