Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606150, here are decompositions:

53 + 31606097 = 31606150
71 + 31606079 = 31606150
83 + 31606067 = 31606150
89 + 31606061 = 31606150
101 + 31606049 = 31606150
167 + 31605983 = 31606150
179 + 31605971 = 31606150
197 + 31605953 = 31606150

Showing the first eight; more decompositions exist.
