Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523388, here are decompositions:

31 + 523357 = 523388
37 + 523351 = 523388
127 + 523261 = 523388
181 + 523207 = 523388
211 + 523177 = 523388
367 + 523021 = 523388
577 + 522811 = 523388
601 + 522787 = 523388

Showing the first eight; more decompositions exist.
