Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523278, here are decompositions:

17 + 523261 = 523278
59 + 523219 = 523278
71 + 523207 = 523278
101 + 523177 = 523278
109 + 523169 = 523278
149 + 523129 = 523278
181 + 523097 = 523278
229 + 523049 = 523278

Showing the first eight; more decompositions exist.
