Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038790, here are decompositions:

59 + 1038731 = 1038790
83 + 1038707 = 1038790
101 + 1038689 = 1038790
167 + 1038623 = 1038790
173 + 1038617 = 1038790
191 + 1038599 = 1038790
227 + 1038563 = 1038790
251 + 1038539 = 1038790

Showing the first eight; more decompositions exist.
