Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722026, here are decompositions:

7 + 8722019 = 8722026
17 + 8722009 = 8722026
29 + 8721997 = 8722026
37 + 8721989 = 8722026
97 + 8721929 = 8722026
109 + 8721917 = 8722026
113 + 8721913 = 8722026
149 + 8721877 = 8722026

Showing the first eight; more decompositions exist.
