Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722146, here are decompositions:

23 + 8722123 = 8722146
29 + 8722117 = 8722146
47 + 8722099 = 8722146
53 + 8722093 = 8722146
67 + 8722079 = 8722146
113 + 8722033 = 8722146
127 + 8722019 = 8722146
137 + 8722009 = 8722146

Showing the first eight; more decompositions exist.
