Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722038, here are decompositions:

5 + 8722033 = 8722038
11 + 8722027 = 8722038
19 + 8722019 = 8722038
29 + 8722009 = 8722038
37 + 8722001 = 8722038
41 + 8721997 = 8722038
97 + 8721941 = 8722038
109 + 8721929 = 8722038

Showing the first eight; more decompositions exist.
