Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722032, here are decompositions:

5 + 8722027 = 8722032
13 + 8722019 = 8722032
23 + 8722009 = 8722032
31 + 8722001 = 8722032
43 + 8721989 = 8722032
103 + 8721929 = 8722032
149 + 8721883 = 8722032
181 + 8721851 = 8722032

Showing the first eight; more decompositions exist.
