Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478238, here are decompositions:

31 + 478207 = 478238
67 + 478171 = 478238
109 + 478129 = 478238
127 + 478111 = 478238
139 + 478099 = 478238
151 + 478087 = 478238
199 + 478039 = 478238
499 + 477739 = 478238

Showing the first eight; more decompositions exist.
