Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038780, here are decompositions:

23 + 1038757 = 1038780
53 + 1038727 = 1038780
59 + 1038721 = 1038780
73 + 1038707 = 1038780
89 + 1038691 = 1038780
109 + 1038671 = 1038780
137 + 1038643 = 1038780
151 + 1038629 = 1038780

Showing the first eight; more decompositions exist.
