Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038438, here are decompositions:

17 + 1038421 = 1038438
29 + 1038409 = 1038438
47 + 1038391 = 1038438
101 + 1038337 = 1038438
109 + 1038329 = 1038438
127 + 1038311 = 1038438
131 + 1038307 = 1038438
179 + 1038259 = 1038438

Showing the first eight; more decompositions exist.
