Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606066, here are decompositions:

5 + 31606061 = 31606066
17 + 31606049 = 31606066
83 + 31605983 = 31606066
113 + 31605953 = 31606066
137 + 31605929 = 31606066
257 + 31605809 = 31606066
263 + 31605803 = 31606066
293 + 31605773 = 31606066

Showing the first eight; more decompositions exist.
