Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617052, here are decompositions:

3 + 31617049 = 31617052
23 + 31617029 = 31617052
29 + 31617023 = 31617052
41 + 31617011 = 31617052
53 + 31616999 = 31617052
101 + 31616951 = 31617052
149 + 31616903 = 31617052
359 + 31616693 = 31617052

Showing the first eight; more decompositions exist.
