Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628334, here are decompositions:

7 + 31628327 = 31628334
43 + 31628291 = 31628334
61 + 31628273 = 31628334
163 + 31628171 = 31628334
167 + 31628167 = 31628334
173 + 31628161 = 31628334
233 + 31628101 = 31628334
313 + 31628021 = 31628334

Showing the first eight; more decompositions exist.
