Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595812, here are decompositions:

5 + 31595807 = 31595812
29 + 31595783 = 31595812
41 + 31595771 = 31595812
89 + 31595723 = 31595812
239 + 31595573 = 31595812
419 + 31595393 = 31595812
449 + 31595363 = 31595812
569 + 31595243 = 31595812

Showing the first eight; more decompositions exist.
