Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595374, here are decompositions:

3 + 31595371 = 31595374
11 + 31595363 = 31595374
101 + 31595273 = 31595374
131 + 31595243 = 31595374
137 + 31595237 = 31595374
197 + 31595177 = 31595374
233 + 31595141 = 31595374
311 + 31595063 = 31595374

Showing the first eight; more decompositions exist.
