Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109724, here are decompositions:

3 + 109721 = 109724
7 + 109717 = 109724
61 + 109663 = 109724
103 + 109621 = 109724
127 + 109597 = 109724
157 + 109567 = 109724
271 + 109453 = 109724
283 + 109441 = 109724

Showing the first eight; more decompositions exist.
