Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606164, here are decompositions:

67 + 31606097 = 31606164
97 + 31606067 = 31606164
103 + 31606061 = 31606164
113 + 31606051 = 31606164
181 + 31605983 = 31606164
193 + 31605971 = 31606164
211 + 31605953 = 31606164
251 + 31605913 = 31606164

Showing the first eight; more decompositions exist.
