Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554342, here are decompositions:

5 + 31554337 = 31554342
59 + 31554283 = 31554342
101 + 31554241 = 31554342
163 + 31554179 = 31554342
179 + 31554163 = 31554342
181 + 31554161 = 31554342
199 + 31554143 = 31554342
269 + 31554073 = 31554342

Showing the first eight; more decompositions exist.
