Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538372, here are decompositions:

5 + 538367 = 538372
41 + 538331 = 538372
71 + 538301 = 538372
89 + 538283 = 538372
113 + 538259 = 538372
173 + 538199 = 538372
251 + 538121 = 538372
293 + 538079 = 538372

Showing the first eight; more decompositions exist.
