Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617896, here are decompositions:

7 + 31617889 = 31617896
19 + 31617877 = 31617896
43 + 31617853 = 31617896
139 + 31617757 = 31617896
199 + 31617697 = 31617896
223 + 31617673 = 31617896
229 + 31617667 = 31617896
313 + 31617583 = 31617896

Showing the first eight; more decompositions exist.
