Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467432, here are decompositions:

13 + 31467419 = 31467432
43 + 31467389 = 31467432
103 + 31467329 = 31467432
131 + 31467301 = 31467432
173 + 31467259 = 31467432
181 + 31467251 = 31467432
229 + 31467203 = 31467432
233 + 31467199 = 31467432

Showing the first eight; more decompositions exist.
