Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019386, here are decompositions:

29 + 1019357 = 1019386
47 + 1019339 = 1019386
89 + 1019297 = 1019386
113 + 1019273 = 1019386
149 + 1019237 = 1019386
257 + 1019129 = 1019386
293 + 1019093 = 1019386
317 + 1019069 = 1019386

Showing the first eight; more decompositions exist.
