Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643248, here are decompositions:

37 + 8643211 = 8643248
67 + 8643181 = 8643248
127 + 8643121 = 8643248
139 + 8643109 = 8643248
157 + 8643091 = 8643248
337 + 8642911 = 8643248
409 + 8642839 = 8643248
487 + 8642761 = 8643248

Showing the first eight; more decompositions exist.
