Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466922, here are decompositions:

23 + 31466899 = 31466922
29 + 31466893 = 31466922
73 + 31466849 = 31466922
101 + 31466821 = 31466922
131 + 31466791 = 31466922
163 + 31466759 = 31466922
173 + 31466749 = 31466922
191 + 31466731 = 31466922

Showing the first eight; more decompositions exist.
