Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624994, here are decompositions:

13 + 8624981 = 8624994
41 + 8624953 = 8624994
73 + 8624921 = 8624994
107 + 8624887 = 8624994
113 + 8624881 = 8624994
173 + 8624821 = 8624994
223 + 8624771 = 8624994
241 + 8624753 = 8624994

Showing the first eight; more decompositions exist.
