Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619106, here are decompositions:

89 + 31619017 = 31619106
97 + 31619009 = 31619106
107 + 31618999 = 31619106
157 + 31618949 = 31619106
163 + 31618943 = 31619106
223 + 31618883 = 31619106
227 + 31618879 = 31619106
257 + 31618849 = 31619106

Showing the first eight; more decompositions exist.
