Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595922, here are decompositions:

41 + 31595881 = 31595922
53 + 31595869 = 31595922
89 + 31595833 = 31595922
139 + 31595783 = 31595922
151 + 31595771 = 31595922
191 + 31595731 = 31595922
199 + 31595723 = 31595922
251 + 31595671 = 31595922

Showing the first eight; more decompositions exist.
