Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568846, here are decompositions:

3 + 31568843 = 31568846
7 + 31568839 = 31568846
13 + 31568833 = 31568846
19 + 31568827 = 31568846
37 + 31568809 = 31568846
79 + 31568767 = 31568846
97 + 31568749 = 31568846
103 + 31568743 = 31568846

Showing the first eight; more decompositions exist.
