Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538090, here are decompositions:

11 + 538079 = 538090
17 + 538073 = 538090
41 + 538049 = 538090
71 + 538019 = 538090
89 + 538001 = 538090
149 + 537941 = 538090
191 + 537899 = 538090
317 + 537773 = 538090

Showing the first eight; more decompositions exist.
