Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554822, here are decompositions:

11 + 31554811 = 31554822
31 + 31554791 = 31554822
73 + 31554749 = 31554822
83 + 31554739 = 31554822
113 + 31554709 = 31554822
151 + 31554671 = 31554822
163 + 31554659 = 31554822
181 + 31554641 = 31554822

Showing the first eight; more decompositions exist.
