Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553682, here are decompositions:

11 + 31553671 = 31553682
19 + 31553663 = 31553682
23 + 31553659 = 31553682
73 + 31553609 = 31553682
163 + 31553519 = 31553682
179 + 31553503 = 31553682
229 + 31553453 = 31553682
313 + 31553369 = 31553682

Showing the first eight; more decompositions exist.
