Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467312, here are decompositions:

11 + 31467301 = 31467312
53 + 31467259 = 31467312
61 + 31467251 = 31467312
83 + 31467229 = 31467312
109 + 31467203 = 31467312
113 + 31467199 = 31467312
131 + 31467181 = 31467312
179 + 31467133 = 31467312

Showing the first eight; more decompositions exist.
