Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595230, here are decompositions:

11 + 31595219 = 31595230
41 + 31595189 = 31595230
53 + 31595177 = 31595230
89 + 31595141 = 31595230
167 + 31595063 = 31595230
239 + 31594991 = 31595230
269 + 31594961 = 31595230
311 + 31594919 = 31595230

Showing the first eight; more decompositions exist.
