Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722000, here are decompositions:

3 + 8721997 = 8722000
11 + 8721989 = 8722000
59 + 8721941 = 8722000
71 + 8721929 = 8722000
83 + 8721917 = 8722000
149 + 8721851 = 8722000
227 + 8721773 = 8722000
251 + 8721749 = 8722000

Showing the first eight; more decompositions exist.
