Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648904, here are decompositions:

23 + 8648881 = 8648904
37 + 8648867 = 8648904
41 + 8648863 = 8648904
67 + 8648837 = 8648904
71 + 8648833 = 8648904
73 + 8648831 = 8648904
107 + 8648797 = 8648904
113 + 8648791 = 8648904

Showing the first eight; more decompositions exist.
