Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045386, here are decompositions:

19 + 1045367 = 1045386
37 + 1045349 = 1045386
79 + 1045307 = 1045386
109 + 1045277 = 1045386
113 + 1045273 = 1045386
149 + 1045237 = 1045386
157 + 1045229 = 1045386
163 + 1045223 = 1045386

Showing the first eight; more decompositions exist.
