Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003638, here are decompositions:

7 + 1003631 = 1003638
11 + 1003627 = 1003638
17 + 1003621 = 1003638
19 + 1003619 = 1003638
29 + 1003609 = 1003638
37 + 1003601 = 1003638
89 + 1003549 = 1003638
131 + 1003507 = 1003638

Showing the first eight; more decompositions exist.
