Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595802, here are decompositions:

19 + 31595783 = 31595802
31 + 31595771 = 31595802
71 + 31595731 = 31595802
79 + 31595723 = 31595802
83 + 31595719 = 31595802
101 + 31595701 = 31595802
131 + 31595671 = 31595802
149 + 31595653 = 31595802

Showing the first eight; more decompositions exist.
