Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628100, here are decompositions:

3 + 8628097 = 8628100
23 + 8628077 = 8628100
83 + 8628017 = 8628100
113 + 8627987 = 8628100
191 + 8627909 = 8628100
197 + 8627903 = 8628100
233 + 8627867 = 8628100
293 + 8627807 = 8628100

Showing the first eight; more decompositions exist.
