Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595376, here are decompositions:

5 + 31595371 = 31595376
13 + 31595363 = 31595376
97 + 31595279 = 31595376
103 + 31595273 = 31595376
139 + 31595237 = 31595376
157 + 31595219 = 31595376
167 + 31595209 = 31595376
199 + 31595177 = 31595376

Showing the first eight; more decompositions exist.
