Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628184, here are decompositions:

11 + 31628173 = 31628184
13 + 31628171 = 31628184
17 + 31628167 = 31628184
23 + 31628161 = 31628184
83 + 31628101 = 31628184
163 + 31628021 = 31628184
167 + 31628017 = 31628184
173 + 31628011 = 31628184

Showing the first eight; more decompositions exist.
