Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595902, here are decompositions:

29 + 31595873 = 31595902
71 + 31595831 = 31595902
131 + 31595771 = 31595902
179 + 31595723 = 31595902
419 + 31595483 = 31595902
509 + 31595393 = 31595902
659 + 31595243 = 31595902
683 + 31595219 = 31595902

Showing the first eight; more decompositions exist.
