Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538078, here are decompositions:

5 + 538073 = 538078
29 + 538049 = 538078
59 + 538019 = 538078
137 + 537941 = 538078
179 + 537899 = 538078
467 + 537611 = 538078
479 + 537599 = 538078
491 + 537587 = 538078

Showing the first eight; more decompositions exist.
