Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697844, here are decompositions:

11 + 8697833 = 8697844
41 + 8697803 = 8697844
47 + 8697797 = 8697844
53 + 8697791 = 8697844
137 + 8697707 = 8697844
167 + 8697677 = 8697844
257 + 8697587 = 8697844
263 + 8697581 = 8697844

Showing the first eight; more decompositions exist.
