Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478182, here are decompositions:

11 + 478171 = 478182
13 + 478169 = 478182
43 + 478139 = 478182
53 + 478129 = 478182
71 + 478111 = 478182
83 + 478099 = 478182
113 + 478069 = 478182
181 + 478001 = 478182

Showing the first eight; more decompositions exist.
