Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621804, here are decompositions:

7 + 8621797 = 8621804
31 + 8621773 = 8621804
97 + 8621707 = 8621804
127 + 8621677 = 8621804
151 + 8621653 = 8621804
181 + 8621623 = 8621804
223 + 8621581 = 8621804
313 + 8621491 = 8621804

Showing the first eight; more decompositions exist.
