Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626896, here are decompositions:

3 + 31626893 = 31626896
13 + 31626883 = 31626896
109 + 31626787 = 31626896
229 + 31626667 = 31626896
277 + 31626619 = 31626896
307 + 31626589 = 31626896
349 + 31626547 = 31626896
397 + 31626499 = 31626896

Showing the first eight; more decompositions exist.
