Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523638, here are decompositions:

7 + 523631 = 523638
41 + 523597 = 523638
61 + 523577 = 523638
67 + 523571 = 523638
97 + 523541 = 523638
127 + 523511 = 523638
149 + 523489 = 523638
151 + 523487 = 523638

Showing the first eight; more decompositions exist.
