Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643272, here are decompositions:

61 + 8643211 = 8643272
73 + 8643199 = 8643272
139 + 8643133 = 8643272
151 + 8643121 = 8643272
163 + 8643109 = 8643272
181 + 8643091 = 8643272
283 + 8642989 = 8643272
409 + 8642863 = 8643272

Showing the first eight; more decompositions exist.
