Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606854, here are decompositions:

7 + 31606847 = 31606854
43 + 31606811 = 31606854
101 + 31606753 = 31606854
113 + 31606741 = 31606854
127 + 31606727 = 31606854
151 + 31606703 = 31606854
157 + 31606697 = 31606854
163 + 31606691 = 31606854

Showing the first eight; more decompositions exist.
