Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467072, here are decompositions:

5 + 31467067 = 31467072
61 + 31467011 = 31467072
73 + 31466999 = 31467072
79 + 31466993 = 31467072
83 + 31466989 = 31467072
103 + 31466969 = 31467072
139 + 31466933 = 31467072
173 + 31466899 = 31467072

Showing the first eight; more decompositions exist.
