Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744920, here are decompositions:

3 + 8744917 = 8744920
11 + 8744909 = 8744920
17 + 8744903 = 8744920
29 + 8744891 = 8744920
59 + 8744861 = 8744920
83 + 8744837 = 8744920
89 + 8744831 = 8744920
101 + 8744819 = 8744920

Showing the first eight; more decompositions exist.
