Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038402, here are decompositions:

11 + 1038391 = 1038402
19 + 1038383 = 1038402
73 + 1038329 = 1038402
83 + 1038319 = 1038402
139 + 1038263 = 1038402
149 + 1038253 = 1038402
151 + 1038251 = 1038402
191 + 1038211 = 1038402

Showing the first eight; more decompositions exist.
