Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523166, here are decompositions:

5 + 31523161 = 31523166
23 + 31523143 = 31523166
47 + 31523119 = 31523166
53 + 31523113 = 31523166
67 + 31523099 = 31523166
113 + 31523053 = 31523166
139 + 31523027 = 31523166
163 + 31523003 = 31523166

Showing the first eight; more decompositions exist.
