Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628214, here are decompositions:

41 + 31628173 = 31628214
43 + 31628171 = 31628214
47 + 31628167 = 31628214
53 + 31628161 = 31628214
113 + 31628101 = 31628214
193 + 31628021 = 31628214
197 + 31628017 = 31628214
283 + 31627931 = 31628214

Showing the first eight; more decompositions exist.
