Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547432, here are decompositions:

19 + 31547413 = 31547432
151 + 31547281 = 31547432
223 + 31547209 = 31547432
229 + 31547203 = 31547432
271 + 31547161 = 31547432
331 + 31547101 = 31547432
463 + 31546969 = 31547432
523 + 31546909 = 31547432

Showing the first eight; more decompositions exist.
