Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613922, here are decompositions:

61 + 31613861 = 31613922
79 + 31613843 = 31613922
83 + 31613839 = 31613922
89 + 31613833 = 31613922
103 + 31613819 = 31613922
139 + 31613783 = 31613922
283 + 31613639 = 31613922
293 + 31613629 = 31613922

Showing the first eight; more decompositions exist.
