Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466994, here are decompositions:

5 + 31466989 = 31466994
17 + 31466977 = 31466994
43 + 31466951 = 31466994
61 + 31466933 = 31466994
101 + 31466893 = 31466994
127 + 31466867 = 31466994
137 + 31466857 = 31466994
173 + 31466821 = 31466994

Showing the first eight; more decompositions exist.
