Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595370, here are decompositions:

7 + 31595363 = 31595370
97 + 31595273 = 31595370
127 + 31595243 = 31595370
151 + 31595219 = 31595370
181 + 31595189 = 31595370
193 + 31595177 = 31595370
197 + 31595173 = 31595370
229 + 31595141 = 31595370

Showing the first eight; more decompositions exist.
