Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024390, here are decompositions:

11 + 1024379 = 1024390
53 + 1024337 = 1024390
71 + 1024319 = 1024390
83 + 1024307 = 1024390
113 + 1024277 = 1024390
239 + 1024151 = 1024390
317 + 1024073 = 1024390
359 + 1024031 = 1024390

Showing the first eight; more decompositions exist.
