Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611072, here are decompositions:

5 + 31611067 = 31611072
23 + 31611049 = 31611072
29 + 31611043 = 31611072
43 + 31611029 = 31611072
61 + 31611011 = 31611072
179 + 31610893 = 31611072
281 + 31610791 = 31611072
293 + 31610779 = 31611072

Showing the first eight; more decompositions exist.
