Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736878, here are decompositions:

61 + 8736817 = 8736878
79 + 8736799 = 8736878
97 + 8736781 = 8736878
151 + 8736727 = 8736878
211 + 8736667 = 8736878
331 + 8736547 = 8736878
349 + 8736529 = 8736878
691 + 8736187 = 8736878

Showing the first eight; more decompositions exist.
