Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706980, here are decompositions:

13 + 8706967 = 8706980
19 + 8706961 = 8706980
43 + 8706937 = 8706980
109 + 8706871 = 8706980
127 + 8706853 = 8706980
151 + 8706829 = 8706980
157 + 8706823 = 8706980
229 + 8706751 = 8706980

Showing the first eight; more decompositions exist.
