Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627484, here are decompositions:

73 + 31627411 = 31627484
127 + 31627357 = 31627484
151 + 31627333 = 31627484
181 + 31627303 = 31627484
223 + 31627261 = 31627484
241 + 31627243 = 31627484
283 + 31627201 = 31627484
433 + 31627051 = 31627484

Showing the first eight; more decompositions exist.
