Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689444, here are decompositions:

11 + 8689433 = 8689444
227 + 8689217 = 8689444
263 + 8689181 = 8689444
311 + 8689133 = 8689444
347 + 8689097 = 8689444
653 + 8688791 = 8689444
773 + 8688671 = 8689444
887 + 8688557 = 8689444

Showing the first eight; more decompositions exist.
