Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536896, here are decompositions:

67 + 31536829 = 31536896
73 + 31536823 = 31536896
103 + 31536793 = 31536896
163 + 31536733 = 31536896
199 + 31536697 = 31536896
283 + 31536613 = 31536896
367 + 31536529 = 31536896
397 + 31536499 = 31536896

Showing the first eight; more decompositions exist.
