Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467030, here are decompositions:

19 + 31467011 = 31467030
31 + 31466999 = 31467030
37 + 31466993 = 31467030
41 + 31466989 = 31467030
53 + 31466977 = 31467030
61 + 31466969 = 31467030
79 + 31466951 = 31467030
97 + 31466933 = 31467030

Showing the first eight; more decompositions exist.
