Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606212, here are decompositions:

31 + 31606181 = 31606212
151 + 31606061 = 31606212
163 + 31606049 = 31606212
229 + 31605983 = 31606212
241 + 31605971 = 31606212
283 + 31605929 = 31606212
389 + 31605823 = 31606212
401 + 31605811 = 31606212

Showing the first eight; more decompositions exist.
