Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538342, here are decompositions:

11 + 538331 = 538342
41 + 538301 = 538342
59 + 538283 = 538342
83 + 538259 = 538342
179 + 538163 = 538342
191 + 538151 = 538342
263 + 538079 = 538342
269 + 538073 = 538342

Showing the first eight; more decompositions exist.
