Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019408, here are decompositions:

31 + 1019377 = 1019408
79 + 1019329 = 1019408
127 + 1019281 = 1019408
151 + 1019257 = 1019408
157 + 1019251 = 1019408
199 + 1019209 = 1019408
211 + 1019197 = 1019408
331 + 1019077 = 1019408

Showing the first eight; more decompositions exist.
