Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706978, here are decompositions:

11 + 8706967 = 8706978
17 + 8706961 = 8706978
31 + 8706947 = 8706978
41 + 8706937 = 8706978
97 + 8706881 = 8706978
107 + 8706871 = 8706978
109 + 8706869 = 8706978
149 + 8706829 = 8706978

Showing the first eight; more decompositions exist.
