Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595368, here are decompositions:

5 + 31595363 = 31595368
89 + 31595279 = 31595368
131 + 31595237 = 31595368
149 + 31595219 = 31595368
179 + 31595189 = 31595368
191 + 31595177 = 31595368
227 + 31595141 = 31595368
347 + 31595021 = 31595368

Showing the first eight; more decompositions exist.
