Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595974, here are decompositions:

5 + 31595969 = 31595974
101 + 31595873 = 31595974
107 + 31595867 = 31595974
167 + 31595807 = 31595974
191 + 31595783 = 31595974
197 + 31595777 = 31595974
251 + 31595723 = 31595974
257 + 31595717 = 31595974

Showing the first eight; more decompositions exist.
