Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736978, here are decompositions:

59 + 8736919 = 8736978
67 + 8736911 = 8736978
71 + 8736907 = 8736978
79 + 8736899 = 8736978
97 + 8736881 = 8736978
179 + 8736799 = 8736978
191 + 8736787 = 8736978
197 + 8736781 = 8736978

Showing the first eight; more decompositions exist.
