Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618844, here are decompositions:

11 + 8618833 = 8618844
61 + 8618783 = 8618844
97 + 8618747 = 8618844
107 + 8618737 = 8618844
163 + 8618681 = 8618844
251 + 8618593 = 8618844
263 + 8618581 = 8618844
277 + 8618567 = 8618844

Showing the first eight; more decompositions exist.
