Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595316, here are decompositions:

37 + 31595279 = 31595316
43 + 31595273 = 31595316
73 + 31595243 = 31595316
79 + 31595237 = 31595316
97 + 31595219 = 31595316
107 + 31595209 = 31595316
127 + 31595189 = 31595316
139 + 31595177 = 31595316

Showing the first eight; more decompositions exist.
