Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648100, here are decompositions:

7 + 8648093 = 8648100
17 + 8648083 = 8648100
67 + 8648033 = 8648100
103 + 8647997 = 8648100
107 + 8647993 = 8648100
137 + 8647963 = 8648100
151 + 8647949 = 8648100
163 + 8647937 = 8648100

Showing the first eight; more decompositions exist.
