Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538222, here are decompositions:

23 + 538199 = 538222
59 + 538163 = 538222
71 + 538151 = 538222
101 + 538121 = 538222
149 + 538073 = 538222
173 + 538049 = 538222
281 + 537941 = 538222
449 + 537773 = 538222

Showing the first eight; more decompositions exist.
