Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606102, here are decompositions:

5 + 31606097 = 31606102
23 + 31606079 = 31606102
41 + 31606061 = 31606102
53 + 31606049 = 31606102
131 + 31605971 = 31606102
149 + 31605953 = 31606102
173 + 31605929 = 31606102
293 + 31605809 = 31606102

Showing the first eight; more decompositions exist.
