Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019340, here are decompositions:

11 + 1019329 = 1019340
43 + 1019297 = 1019340
59 + 1019281 = 1019340
67 + 1019273 = 1019340
73 + 1019267 = 1019340
79 + 1019261 = 1019340
83 + 1019257 = 1019340
89 + 1019251 = 1019340

Showing the first eight; more decompositions exist.
