Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038720, here are decompositions:

13 + 1038707 = 1038720
29 + 1038691 = 1038720
31 + 1038689 = 1038720
83 + 1038637 = 1038720
97 + 1038623 = 1038720
101 + 1038619 = 1038720
103 + 1038617 = 1038720
131 + 1038589 = 1038720

Showing the first eight; more decompositions exist.
