Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547252, here are decompositions:

43 + 31547209 = 31547252
109 + 31547143 = 31547252
151 + 31547101 = 31547252
271 + 31546981 = 31547252
283 + 31546969 = 31547252
409 + 31546843 = 31547252
421 + 31546831 = 31547252
439 + 31546813 = 31547252

Showing the first eight; more decompositions exist.
