Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648884, here are decompositions:

3 + 8648881 = 8648884
5 + 8648879 = 8648884
17 + 8648867 = 8648884
47 + 8648837 = 8648884
53 + 8648831 = 8648884
71 + 8648813 = 8648884
137 + 8648747 = 8648884
197 + 8648687 = 8648884

Showing the first eight; more decompositions exist.
