Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467234, here are decompositions:

5 + 31467229 = 31467234
31 + 31467203 = 31467234
53 + 31467181 = 31467234
67 + 31467167 = 31467234
101 + 31467133 = 31467234
107 + 31467127 = 31467234
131 + 31467103 = 31467234
151 + 31467083 = 31467234

Showing the first eight; more decompositions exist.
