Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654128, here are decompositions:

5 + 8654123 = 8654128
11 + 8654117 = 8654128
17 + 8654111 = 8654128
29 + 8654099 = 8654128
71 + 8654057 = 8654128
89 + 8654039 = 8654128
101 + 8654027 = 8654128
107 + 8654021 = 8654128

Showing the first eight; more decompositions exist.
