Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643444, here are decompositions:

11 + 8643433 = 8643444
101 + 8643343 = 8643444
107 + 8643337 = 8643444
127 + 8643317 = 8643444
137 + 8643307 = 8643444
157 + 8643287 = 8643444
163 + 8643281 = 8643444
233 + 8643211 = 8643444

Showing the first eight; more decompositions exist.
