Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722030, here are decompositions:

3 + 8722027 = 8722030
11 + 8722019 = 8722030
29 + 8722001 = 8722030
41 + 8721989 = 8722030
89 + 8721941 = 8722030
101 + 8721929 = 8722030
113 + 8721917 = 8722030
179 + 8721851 = 8722030

Showing the first eight; more decompositions exist.
