Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038540, here are decompositions:

11 + 1038529 = 1038540
17 + 1038523 = 1038540
37 + 1038503 = 1038540
43 + 1038497 = 1038540
53 + 1038487 = 1038540
131 + 1038409 = 1038540
149 + 1038391 = 1038540
157 + 1038383 = 1038540

Showing the first eight; more decompositions exist.
