Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547028, here are decompositions:

31 + 31546997 = 31547028
41 + 31546987 = 31547028
47 + 31546981 = 31547028
59 + 31546969 = 31547028
137 + 31546891 = 31547028
167 + 31546861 = 31547028
181 + 31546847 = 31547028
197 + 31546831 = 31547028

Showing the first eight; more decompositions exist.
