Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722044, here are decompositions:

11 + 8722033 = 8722044
17 + 8722027 = 8722044
43 + 8722001 = 8722044
47 + 8721997 = 8722044
103 + 8721941 = 8722044
127 + 8721917 = 8722044
131 + 8721913 = 8722044
137 + 8721907 = 8722044

Showing the first eight; more decompositions exist.
