Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595382, here are decompositions:

11 + 31595371 = 31595382
19 + 31595363 = 31595382
103 + 31595279 = 31595382
109 + 31595273 = 31595382
131 + 31595251 = 31595382
139 + 31595243 = 31595382
163 + 31595219 = 31595382
173 + 31595209 = 31595382

Showing the first eight; more decompositions exist.
