Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538288, here are decompositions:

5 + 538283 = 538288
29 + 538259 = 538288
41 + 538247 = 538288
89 + 538199 = 538288
131 + 538157 = 538288
137 + 538151 = 538288
167 + 538121 = 538288
239 + 538049 = 538288

Showing the first eight; more decompositions exist.
