Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547372, here are decompositions:

163 + 31547209 = 31547372
211 + 31547161 = 31547372
229 + 31547143 = 31547372
271 + 31547101 = 31547372
463 + 31546909 = 31547372
541 + 31546831 = 31547372
613 + 31546759 = 31547372
631 + 31546741 = 31547372

Showing the first eight; more decompositions exist.
