Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595214, here are decompositions:

5 + 31595209 = 31595214
37 + 31595177 = 31595214
41 + 31595173 = 31595214
73 + 31595141 = 31595214
113 + 31595101 = 31595214
151 + 31595063 = 31595214
193 + 31595021 = 31595214
223 + 31594991 = 31595214

Showing the first eight; more decompositions exist.
