Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663978, here are decompositions:

19 + 8663959 = 8663978
79 + 8663899 = 8663978
109 + 8663869 = 8663978
151 + 8663827 = 8663978
157 + 8663821 = 8663978
181 + 8663797 = 8663978
277 + 8663701 = 8663978
457 + 8663521 = 8663978

Showing the first eight; more decompositions exist.
