Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595892, here are decompositions:

11 + 31595881 = 31595892
19 + 31595873 = 31595892
23 + 31595869 = 31595892
59 + 31595833 = 31595892
61 + 31595831 = 31595892
109 + 31595783 = 31595892
173 + 31595719 = 31595892
191 + 31595701 = 31595892

Showing the first eight; more decompositions exist.
