Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467012, here are decompositions:

13 + 31466999 = 31467012
19 + 31466993 = 31467012
23 + 31466989 = 31467012
43 + 31466969 = 31467012
61 + 31466951 = 31467012
79 + 31466933 = 31467012
113 + 31466899 = 31467012
139 + 31466873 = 31467012

Showing the first eight; more decompositions exist.
