Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554330, here are decompositions:

43 + 31554287 = 31554330
47 + 31554283 = 31554330
89 + 31554241 = 31554330
131 + 31554199 = 31554330
149 + 31554181 = 31554330
151 + 31554179 = 31554330
167 + 31554163 = 31554330
257 + 31554073 = 31554330

Showing the first eight; more decompositions exist.
