Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553996, here are decompositions:

3 + 31553993 = 31553996
13 + 31553983 = 31553996
163 + 31553833 = 31553996
193 + 31553803 = 31553996
277 + 31553719 = 31553996
337 + 31553659 = 31553996
379 + 31553617 = 31553996
613 + 31553383 = 31553996

Showing the first eight; more decompositions exist.
