Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595308, here are decompositions:

29 + 31595279 = 31595308
71 + 31595237 = 31595308
89 + 31595219 = 31595308
131 + 31595177 = 31595308
167 + 31595141 = 31595308
317 + 31594991 = 31595308
347 + 31594961 = 31595308
389 + 31594919 = 31595308

Showing the first eight; more decompositions exist.
