Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112818, here are decompositions:

11 + 112807 = 112818
19 + 112799 = 112818
31 + 112787 = 112818
47 + 112771 = 112818
59 + 112759 = 112818
61 + 112757 = 112818
127 + 112691 = 112818
131 + 112687 = 112818

Showing the first eight; more decompositions exist.
