Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538224, here are decompositions:

23 + 538201 = 538224
61 + 538163 = 538224
67 + 538157 = 538224
73 + 538151 = 538224
97 + 538127 = 538224
101 + 538123 = 538224
103 + 538121 = 538224
107 + 538117 = 538224

Showing the first eight; more decompositions exist.
