Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523238, here are decompositions:

19 + 523219 = 523238
31 + 523207 = 523238
61 + 523177 = 523238
109 + 523129 = 523238
277 + 522961 = 523238
367 + 522871 = 523238
409 + 522829 = 523238
577 + 522661 = 523238

Showing the first eight; more decompositions exist.
