Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467402, here are decompositions:

13 + 31467389 = 31467402
73 + 31467329 = 31467402
101 + 31467301 = 31467402
151 + 31467251 = 31467402
173 + 31467229 = 31467402
199 + 31467203 = 31467402
233 + 31467169 = 31467402
269 + 31467133 = 31467402

Showing the first eight; more decompositions exist.
