Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613070, here are decompositions:

17 + 31613053 = 31613070
43 + 31613027 = 31613070
79 + 31612991 = 31613070
89 + 31612981 = 31613070
101 + 31612969 = 31613070
109 + 31612961 = 31613070
131 + 31612939 = 31613070
157 + 31612913 = 31613070

Showing the first eight; more decompositions exist.
