Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554222, here are decompositions:

23 + 31554199 = 31554222
41 + 31554181 = 31554222
43 + 31554179 = 31554222
59 + 31554163 = 31554222
61 + 31554161 = 31554222
79 + 31554143 = 31554222
101 + 31554121 = 31554222
149 + 31554073 = 31554222

Showing the first eight; more decompositions exist.
