Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615052, here are decompositions:

13 + 31615039 = 31615052
109 + 31614943 = 31615052
163 + 31614889 = 31615052
193 + 31614859 = 31615052
199 + 31614853 = 31615052
223 + 31614829 = 31615052
283 + 31614769 = 31615052
349 + 31614703 = 31615052

Showing the first eight; more decompositions exist.
