Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466162, here are decompositions:

19 + 31466143 = 31466162
43 + 31466119 = 31466162
61 + 31466101 = 31466162
73 + 31466089 = 31466162
109 + 31466053 = 31466162
163 + 31465999 = 31466162
271 + 31465891 = 31466162
283 + 31465879 = 31466162

Showing the first eight; more decompositions exist.
