Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596668, here are decompositions:

7 + 31596661 = 31596668
31 + 31596637 = 31596668
97 + 31596571 = 31596668
127 + 31596541 = 31596668
157 + 31596511 = 31596668
277 + 31596391 = 31596668
541 + 31596127 = 31596668
547 + 31596121 = 31596668

Showing the first eight; more decompositions exist.
