Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618914, here are decompositions:

13 + 31618901 = 31618914
17 + 31618897 = 31618914
23 + 31618891 = 31618914
31 + 31618883 = 31618914
43 + 31618871 = 31618914
137 + 31618777 = 31618914
163 + 31618751 = 31618914
211 + 31618703 = 31618914

Showing the first eight; more decompositions exist.
