Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554422, here are decompositions:

13 + 31554409 = 31554422
61 + 31554361 = 31554422
139 + 31554283 = 31554422
181 + 31554241 = 31554422
223 + 31554199 = 31554422
241 + 31554181 = 31554422
349 + 31554073 = 31554422
379 + 31554043 = 31554422

Showing the first eight; more decompositions exist.
