Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618934, here are decompositions:

37 + 31618897 = 31618934
43 + 31618891 = 31618934
157 + 31618777 = 31618934
163 + 31618771 = 31618934
181 + 31618753 = 31618934
223 + 31618711 = 31618934
241 + 31618693 = 31618934
271 + 31618663 = 31618934

Showing the first eight; more decompositions exist.
