Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478188, here are decompositions:

17 + 478171 = 478188
19 + 478169 = 478188
31 + 478157 = 478188
59 + 478129 = 478188
89 + 478099 = 478188
101 + 478087 = 478188
149 + 478039 = 478188
197 + 477991 = 478188

Showing the first eight; more decompositions exist.
