Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467456, here are decompositions:

19 + 31467437 = 31467456
23 + 31467433 = 31467456
37 + 31467419 = 31467456
67 + 31467389 = 31467456
89 + 31467367 = 31467456
109 + 31467347 = 31467456
127 + 31467329 = 31467456
197 + 31467259 = 31467456

Showing the first eight; more decompositions exist.
