Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627284, here are decompositions:

23 + 31627261 = 31627284
37 + 31627247 = 31627284
41 + 31627243 = 31627284
47 + 31627237 = 31627284
67 + 31627217 = 31627284
83 + 31627201 = 31627284
151 + 31627133 = 31627284
163 + 31627121 = 31627284

Showing the first eight; more decompositions exist.
