Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642976, here are decompositions:

29 + 8642947 = 8642976
37 + 8642939 = 8642976
73 + 8642903 = 8642976
79 + 8642897 = 8642976
113 + 8642863 = 8642976
127 + 8642849 = 8642976
137 + 8642839 = 8642976
157 + 8642819 = 8642976

Showing the first eight; more decompositions exist.
