Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008838, here are decompositions:

29 + 1008809 = 1008838
59 + 1008779 = 1008838
137 + 1008701 = 1008838
179 + 1008659 = 1008838
227 + 1008611 = 1008838
251 + 1008587 = 1008838
401 + 1008437 = 1008838
419 + 1008419 = 1008838

Showing the first eight; more decompositions exist.
