Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606090, here are decompositions:

3 + 31606087 = 31606090
11 + 31606079 = 31606090
23 + 31606067 = 31606090
29 + 31606061 = 31606090
41 + 31606049 = 31606090
107 + 31605983 = 31606090
137 + 31605953 = 31606090
281 + 31605809 = 31606090

Showing the first eight; more decompositions exist.
