Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643844, here are decompositions:

5 + 8643839 = 8643844
23 + 8643821 = 8643844
47 + 8643797 = 8643844
137 + 8643707 = 8643844
173 + 8643671 = 8643844
197 + 8643647 = 8643844
257 + 8643587 = 8643844
281 + 8643563 = 8643844

Showing the first eight; more decompositions exist.
