Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553796, here are decompositions:

13 + 31553783 = 31553796
19 + 31553777 = 31553796
37 + 31553759 = 31553796
67 + 31553729 = 31553796
89 + 31553707 = 31553796
137 + 31553659 = 31553796
179 + 31553617 = 31553796
269 + 31553527 = 31553796

Showing the first eight; more decompositions exist.
