Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466962, here are decompositions:

11 + 31466951 = 31466962
29 + 31466933 = 31466962
89 + 31466873 = 31466962
113 + 31466849 = 31466962
269 + 31466693 = 31466962
911 + 31466051 = 31466962
983 + 31465979 = 31466962
1181 + 31465781 = 31466962

Showing the first eight; more decompositions exist.
