Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595862, here are decompositions:

29 + 31595833 = 31595862
31 + 31595831 = 31595862
79 + 31595783 = 31595862
131 + 31595731 = 31595862
139 + 31595723 = 31595862
191 + 31595671 = 31595862
251 + 31595611 = 31595862
269 + 31595593 = 31595862

Showing the first eight; more decompositions exist.
