Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595350, here are decompositions:

71 + 31595279 = 31595350
107 + 31595243 = 31595350
113 + 31595237 = 31595350
131 + 31595219 = 31595350
173 + 31595177 = 31595350
359 + 31594991 = 31595350
389 + 31594961 = 31595350
419 + 31594931 = 31595350

Showing the first eight; more decompositions exist.
