Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648040, here are decompositions:

7 + 8648033 = 8648040
43 + 8647997 = 8648040
47 + 8647993 = 8648040
61 + 8647979 = 8648040
73 + 8647967 = 8648040
103 + 8647937 = 8648040
113 + 8647927 = 8648040
127 + 8647913 = 8648040

Showing the first eight; more decompositions exist.
