Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596722, here are decompositions:

13 + 31596709 = 31596722
43 + 31596679 = 31596722
61 + 31596661 = 31596722
109 + 31596613 = 31596722
139 + 31596583 = 31596722
151 + 31596571 = 31596722
181 + 31596541 = 31596722
211 + 31596511 = 31596722

Showing the first eight; more decompositions exist.
