Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606072, here are decompositions:

5 + 31606067 = 31606072
11 + 31606061 = 31606072
23 + 31606049 = 31606072
89 + 31605983 = 31606072
101 + 31605971 = 31606072
263 + 31605809 = 31606072
269 + 31605803 = 31606072
293 + 31605779 = 31606072

Showing the first eight; more decompositions exist.
