Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678844, here are decompositions:

11 + 8678833 = 8678844
23 + 8678821 = 8678844
61 + 8678783 = 8678844
67 + 8678777 = 8678844
71 + 8678773 = 8678844
103 + 8678741 = 8678844
131 + 8678713 = 8678844
137 + 8678707 = 8678844

Showing the first eight; more decompositions exist.
