Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618794, here are decompositions:

13 + 31618781 = 31618794
17 + 31618777 = 31618794
23 + 31618771 = 31618794
41 + 31618753 = 31618794
43 + 31618751 = 31618794
83 + 31618711 = 31618794
101 + 31618693 = 31618794
113 + 31618681 = 31618794

Showing the first eight; more decompositions exist.
