Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613010, here are decompositions:

19 + 31612991 = 31613010
29 + 31612981 = 31613010
41 + 31612969 = 31613010
59 + 31612951 = 31613010
71 + 31612939 = 31613010
97 + 31612913 = 31613010
137 + 31612873 = 31613010
157 + 31612853 = 31613010

Showing the first eight; more decompositions exist.
