Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643246, here are decompositions:

23 + 8643223 = 8643246
37 + 8643209 = 8643246
47 + 8643199 = 8643246
97 + 8643149 = 8643246
103 + 8643143 = 8643246
109 + 8643137 = 8643246
113 + 8643133 = 8643246
137 + 8643109 = 8643246

Showing the first eight; more decompositions exist.
