Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547284, here are decompositions:

3 + 31547281 = 31547284
17 + 31547267 = 31547284
23 + 31547261 = 31547284
53 + 31547231 = 31547284
107 + 31547177 = 31547284
137 + 31547147 = 31547284
191 + 31547093 = 31547284
281 + 31547003 = 31547284

Showing the first eight; more decompositions exist.
