Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008390, here are decompositions:

11 + 1008379 = 1008390
17 + 1008373 = 1008390
37 + 1008353 = 1008390
43 + 1008347 = 1008390
59 + 1008331 = 1008390
67 + 1008323 = 1008390
73 + 1008317 = 1008390
127 + 1008263 = 1008390

Showing the first eight; more decompositions exist.
