Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618896, here are decompositions:

5 + 31618891 = 31618896
13 + 31618883 = 31618896
17 + 31618879 = 31618896
47 + 31618849 = 31618896
73 + 31618823 = 31618896
193 + 31618703 = 31618896
227 + 31618669 = 31618896
233 + 31618663 = 31618896

Showing the first eight; more decompositions exist.
