Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038390, here are decompositions:

7 + 1038383 = 1038390
53 + 1038337 = 1038390
61 + 1038329 = 1038390
71 + 1038319 = 1038390
79 + 1038311 = 1038390
83 + 1038307 = 1038390
127 + 1038263 = 1038390
131 + 1038259 = 1038390

Showing the first eight; more decompositions exist.
