Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008638, here are decompositions:

31 + 1008607 = 1008638
67 + 1008571 = 1008638
97 + 1008541 = 1008638
139 + 1008499 = 1008638
229 + 1008409 = 1008638
307 + 1008331 = 1008638
409 + 1008229 = 1008638
439 + 1008199 = 1008638

Showing the first eight; more decompositions exist.
