Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654238, here are decompositions:

7 + 8654231 = 8654238
17 + 8654221 = 8654238
37 + 8654201 = 8654238
67 + 8654171 = 8654238
127 + 8654111 = 8654238
139 + 8654099 = 8654238
149 + 8654089 = 8654238
181 + 8654057 = 8654238

Showing the first eight; more decompositions exist.
