Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618994, here are decompositions:

3 + 31618991 = 31618994
13 + 31618981 = 31618994
97 + 31618897 = 31618994
103 + 31618891 = 31618994
223 + 31618771 = 31618994
241 + 31618753 = 31618994
283 + 31618711 = 31618994
313 + 31618681 = 31618994

Showing the first eight; more decompositions exist.
