Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613946, here are decompositions:

19 + 31613927 = 31613946
79 + 31613867 = 31613946
103 + 31613843 = 31613946
107 + 31613839 = 31613946
113 + 31613833 = 31613946
127 + 31613819 = 31613946
139 + 31613807 = 31613946
149 + 31613797 = 31613946

Showing the first eight; more decompositions exist.
