Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595848, here are decompositions:

17 + 31595831 = 31595848
41 + 31595807 = 31595848
71 + 31595777 = 31595848
131 + 31595717 = 31595848
191 + 31595657 = 31595848
281 + 31595567 = 31595848
461 + 31595387 = 31595848
569 + 31595279 = 31595848

Showing the first eight; more decompositions exist.
