Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467270, here are decompositions:

11 + 31467259 = 31467270
19 + 31467251 = 31467270
41 + 31467229 = 31467270
67 + 31467203 = 31467270
71 + 31467199 = 31467270
89 + 31467181 = 31467270
101 + 31467169 = 31467270
103 + 31467167 = 31467270

Showing the first eight; more decompositions exist.
