Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553822, here are decompositions:

19 + 31553803 = 31553822
61 + 31553761 = 31553822
103 + 31553719 = 31553822
151 + 31553671 = 31553822
163 + 31553659 = 31553822
439 + 31553383 = 31553822
463 + 31553359 = 31553822
661 + 31553161 = 31553822

Showing the first eight; more decompositions exist.
