Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613052, here are decompositions:

61 + 31612991 = 31613052
71 + 31612981 = 31613052
83 + 31612969 = 31613052
101 + 31612951 = 31613052
113 + 31612939 = 31613052
139 + 31612913 = 31613052
179 + 31612873 = 31613052
199 + 31612853 = 31613052

Showing the first eight; more decompositions exist.
