Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553676, here are decompositions:

5 + 31553671 = 31553676
13 + 31553663 = 31553676
17 + 31553659 = 31553676
59 + 31553617 = 31553676
67 + 31553609 = 31553676
149 + 31553527 = 31553676
157 + 31553519 = 31553676
173 + 31553503 = 31553676

Showing the first eight; more decompositions exist.
