Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744928, here are decompositions:

11 + 8744917 = 8744928
19 + 8744909 = 8744928
37 + 8744891 = 8744928
41 + 8744887 = 8744928
67 + 8744861 = 8744928
97 + 8744831 = 8744928
109 + 8744819 = 8744928
191 + 8744737 = 8744928

Showing the first eight; more decompositions exist.
