Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988724, here are decompositions:

13 + 988711 = 988724
31 + 988693 = 988724
43 + 988681 = 988724
73 + 988651 = 988724
223 + 988501 = 988724
241 + 988483 = 988724
271 + 988453 = 988724
307 + 988417 = 988724

Showing the first eight; more decompositions exist.
