Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523508, here are decompositions:

19 + 523489 = 523508
151 + 523357 = 523508
157 + 523351 = 523508
211 + 523297 = 523508
331 + 523177 = 523508
379 + 523129 = 523508
487 + 523021 = 523508
547 + 522961 = 523508

Showing the first eight; more decompositions exist.
