Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466216, here are decompositions:

43 + 31466173 = 31466216
73 + 31466143 = 31466216
79 + 31466137 = 31466216
97 + 31466119 = 31466216
109 + 31466107 = 31466216
127 + 31466089 = 31466216
163 + 31466053 = 31466216
337 + 31465879 = 31466216

Showing the first eight; more decompositions exist.
