Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478226, here are decompositions:

13 + 478213 = 478226
19 + 478207 = 478226
37 + 478189 = 478226
97 + 478129 = 478226
127 + 478099 = 478226
139 + 478087 = 478226
157 + 478069 = 478226
163 + 478063 = 478226

Showing the first eight; more decompositions exist.
