Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628804, here are decompositions:

5 + 8628799 = 8628804
13 + 8628791 = 8628804
17 + 8628787 = 8628804
31 + 8628773 = 8628804
53 + 8628751 = 8628804
127 + 8628677 = 8628804
157 + 8628647 = 8628804
181 + 8628623 = 8628804

Showing the first eight; more decompositions exist.
