Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613082, here are decompositions:

29 + 31613053 = 31613082
101 + 31612981 = 31613082
113 + 31612969 = 31613082
131 + 31612951 = 31613082
191 + 31612891 = 31613082
229 + 31612853 = 31613082
251 + 31612831 = 31613082
349 + 31612733 = 31613082

Showing the first eight; more decompositions exist.
