Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643254, here are decompositions:

31 + 8643223 = 8643254
43 + 8643211 = 8643254
73 + 8643181 = 8643254
163 + 8643091 = 8643254
241 + 8643013 = 8643254
307 + 8642947 = 8643254
397 + 8642857 = 8643254
673 + 8642581 = 8643254

Showing the first eight; more decompositions exist.
