Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613252, here are decompositions:

3 + 31613249 = 31613252
61 + 31613191 = 31613252
109 + 31613143 = 31613252
199 + 31613053 = 31613252
271 + 31612981 = 31613252
283 + 31612969 = 31613252
313 + 31612939 = 31613252
379 + 31612873 = 31613252

Showing the first eight; more decompositions exist.
