Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538388, here are decompositions:

31 + 538357 = 538388
79 + 538309 = 538388
139 + 538249 = 538388
229 + 538159 = 538388
241 + 538147 = 538388
271 + 538117 = 538388
337 + 538051 = 538388
397 + 537991 = 538388

Showing the first eight; more decompositions exist.
