Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538624, here are decompositions:

3 + 538621 = 538624
71 + 538553 = 538624
101 + 538523 = 538624
113 + 538511 = 538624
137 + 538487 = 538624
167 + 538457 = 538624
227 + 538397 = 538624
257 + 538367 = 538624

Showing the first eight; more decompositions exist.
