Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595806, here are decompositions:

23 + 31595783 = 31595806
29 + 31595777 = 31595806
83 + 31595723 = 31595806
89 + 31595717 = 31595806
149 + 31595657 = 31595806
233 + 31595573 = 31595806
239 + 31595567 = 31595806
419 + 31595387 = 31595806

Showing the first eight; more decompositions exist.
