Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722182, here are decompositions:

11 + 8722171 = 8722182
13 + 8722169 = 8722182
59 + 8722123 = 8722182
83 + 8722099 = 8722182
89 + 8722093 = 8722182
101 + 8722081 = 8722182
103 + 8722079 = 8722182
149 + 8722033 = 8722182

Showing the first eight; more decompositions exist.
