Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748018, here are decompositions:

7 + 8748011 = 8748018
17 + 8748001 = 8748018
31 + 8747987 = 8748018
47 + 8747971 = 8748018
61 + 8747957 = 8748018
89 + 8747929 = 8748018
101 + 8747917 = 8748018
127 + 8747891 = 8748018

Showing the first eight; more decompositions exist.
