Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038928, here are decompositions:

47 + 1038881 = 1038928
101 + 1038827 = 1038928
131 + 1038797 = 1038928
197 + 1038731 = 1038928
239 + 1038689 = 1038928
257 + 1038671 = 1038928
311 + 1038617 = 1038928
389 + 1038539 = 1038928

Showing the first eight; more decompositions exist.
