Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744720, here are decompositions:

3 + 8744717 = 8744720
13 + 8744707 = 8744720
37 + 8744683 = 8744720
109 + 8744611 = 8744720
157 + 8744563 = 8744720
163 + 8744557 = 8744720
223 + 8744497 = 8744720
307 + 8744413 = 8744720

Showing the first eight; more decompositions exist.
