Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467288, here are decompositions:

29 + 31467259 = 31467288
37 + 31467251 = 31467288
59 + 31467229 = 31467288
89 + 31467199 = 31467288
107 + 31467181 = 31467288
131 + 31467157 = 31467288
199 + 31467089 = 31467288
277 + 31467011 = 31467288

Showing the first eight; more decompositions exist.
