Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606176, here are decompositions:

79 + 31606097 = 31606176
89 + 31606087 = 31606176
97 + 31606079 = 31606176
109 + 31606067 = 31606176
127 + 31606049 = 31606176
193 + 31605983 = 31606176
223 + 31605953 = 31606176
263 + 31605913 = 31606176

Showing the first eight; more decompositions exist.
