Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613088, here are decompositions:

61 + 31613027 = 31613088
97 + 31612991 = 31613088
107 + 31612981 = 31613088
127 + 31612961 = 31613088
137 + 31612951 = 31613088
149 + 31612939 = 31613088
197 + 31612891 = 31613088
257 + 31612831 = 31613088

Showing the first eight; more decompositions exist.
