Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478320, here are decompositions:

47 + 478273 = 478320
61 + 478259 = 478320
67 + 478253 = 478320
79 + 478241 = 478320
107 + 478213 = 478320
113 + 478207 = 478320
131 + 478189 = 478320
149 + 478171 = 478320

Showing the first eight; more decompositions exist.
