Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550652, here are decompositions:

41 + 31550611 = 31550652
53 + 31550599 = 31550652
59 + 31550593 = 31550652
71 + 31550581 = 31550652
79 + 31550573 = 31550652
83 + 31550569 = 31550652
109 + 31550543 = 31550652
113 + 31550539 = 31550652

Showing the first eight; more decompositions exist.
