Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553726, here are decompositions:

7 + 31553719 = 31553726
19 + 31553707 = 31553726
67 + 31553659 = 31553726
109 + 31553617 = 31553726
199 + 31553527 = 31553726
223 + 31553503 = 31553726
367 + 31553359 = 31553726
709 + 31553017 = 31553726

Showing the first eight; more decompositions exist.
