Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606194, here are decompositions:

7 + 31606187 = 31606194
13 + 31606181 = 31606194
97 + 31606097 = 31606194
107 + 31606087 = 31606194
127 + 31606067 = 31606194
211 + 31605983 = 31606194
223 + 31605971 = 31606194
241 + 31605953 = 31606194

Showing the first eight; more decompositions exist.
