Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538422, here are decompositions:

11 + 538411 = 538422
23 + 538399 = 538422
89 + 538333 = 538422
113 + 538309 = 538422
139 + 538283 = 538422
163 + 538259 = 538422
173 + 538249 = 538422
223 + 538199 = 538422

Showing the first eight; more decompositions exist.
