Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744940, here are decompositions:

11 + 8744929 = 8744940
13 + 8744927 = 8744940
23 + 8744917 = 8744940
31 + 8744909 = 8744940
37 + 8744903 = 8744940
53 + 8744887 = 8744940
79 + 8744861 = 8744940
97 + 8744843 = 8744940

Showing the first eight; more decompositions exist.
