Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538248, here are decompositions:

47 + 538201 = 538248
89 + 538159 = 538248
97 + 538151 = 538248
101 + 538147 = 538248
127 + 538121 = 538248
131 + 538117 = 538248
197 + 538051 = 538248
199 + 538049 = 538248

Showing the first eight; more decompositions exist.
