Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595996, here are decompositions:

7 + 31595989 = 31595996
13 + 31595983 = 31595996
67 + 31595929 = 31595996
127 + 31595869 = 31595996
163 + 31595833 = 31595996
277 + 31595719 = 31595996
613 + 31595383 = 31595996
787 + 31595209 = 31595996

Showing the first eight; more decompositions exist.
