Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654040, here are decompositions:

7 + 8654033 = 8654040
11 + 8654029 = 8654040
13 + 8654027 = 8654040
19 + 8654021 = 8654040
23 + 8654017 = 8654040
29 + 8654011 = 8654040
103 + 8653937 = 8654040
137 + 8653903 = 8654040

Showing the first eight; more decompositions exist.
