Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627548, here are decompositions:

5 + 31627543 = 31627548
11 + 31627537 = 31627548
37 + 31627511 = 31627548
47 + 31627501 = 31627548
137 + 31627411 = 31627548
157 + 31627391 = 31627548
191 + 31627357 = 31627548
229 + 31627319 = 31627548

Showing the first eight; more decompositions exist.
