Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613934, here are decompositions:

7 + 31613927 = 31613934
67 + 31613867 = 31613934
73 + 31613861 = 31613934
101 + 31613833 = 31613934
127 + 31613807 = 31613934
137 + 31613797 = 31613934
151 + 31613783 = 31613934
307 + 31613627 = 31613934

Showing the first eight; more decompositions exist.
