Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654436, here are decompositions:

5 + 8654431 = 8654436
47 + 8654389 = 8654436
79 + 8654357 = 8654436
97 + 8654339 = 8654436
103 + 8654333 = 8654436
137 + 8654299 = 8654436
149 + 8654287 = 8654436
179 + 8654257 = 8654436

Showing the first eight; more decompositions exist.
