Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643146, here are decompositions:

3 + 8643143 = 8643146
13 + 8643133 = 8643146
37 + 8643109 = 8643146
157 + 8642989 = 8643146
199 + 8642947 = 8643146
283 + 8642863 = 8643146
307 + 8642839 = 8643146
373 + 8642773 = 8643146

Showing the first eight; more decompositions exist.
