Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643236, here are decompositions:

13 + 8643223 = 8643236
37 + 8643199 = 8643236
103 + 8643133 = 8643236
127 + 8643109 = 8643236
223 + 8643013 = 8643236
373 + 8642863 = 8643236
379 + 8642857 = 8643236
397 + 8642839 = 8643236

Showing the first eight; more decompositions exist.
