Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648874, here are decompositions:

7 + 8648867 = 8648874
11 + 8648863 = 8648874
37 + 8648837 = 8648874
41 + 8648833 = 8648874
43 + 8648831 = 8648874
61 + 8648813 = 8648874
83 + 8648791 = 8648874
127 + 8648747 = 8648874

Showing the first eight; more decompositions exist.
