Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554414, here are decompositions:

5 + 31554409 = 31554414
13 + 31554401 = 31554414
53 + 31554361 = 31554414
127 + 31554287 = 31554414
131 + 31554283 = 31554414
173 + 31554241 = 31554414
233 + 31554181 = 31554414
251 + 31554163 = 31554414

Showing the first eight; more decompositions exist.
