Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722106, here are decompositions:

7 + 8722099 = 8722106
13 + 8722093 = 8722106
73 + 8722033 = 8722106
79 + 8722027 = 8722106
97 + 8722009 = 8722106
109 + 8721997 = 8722106
193 + 8721913 = 8722106
199 + 8721907 = 8722106

Showing the first eight; more decompositions exist.
