Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606206, here are decompositions:

19 + 31606187 = 31606206
109 + 31606097 = 31606206
127 + 31606079 = 31606206
139 + 31606067 = 31606206
157 + 31606049 = 31606206
223 + 31605983 = 31606206
277 + 31605929 = 31606206
293 + 31605913 = 31606206

Showing the first eight; more decompositions exist.
