Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523328, here are decompositions:

31 + 523297 = 523328
67 + 523261 = 523328
109 + 523219 = 523328
151 + 523177 = 523328
199 + 523129 = 523328
307 + 523021 = 523328
367 + 522961 = 523328
409 + 522919 = 523328

Showing the first eight; more decompositions exist.
