Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481238, here are decompositions:

7 + 481231 = 481238
31 + 481207 = 481238
61 + 481177 = 481238
67 + 481171 = 481238
97 + 481141 = 481238
151 + 481087 = 481238
229 + 481009 = 481238
271 + 480967 = 481238

Showing the first eight; more decompositions exist.
