Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661244, here are decompositions:

3 + 8661241 = 8661244
5 + 8661239 = 8661244
41 + 8661203 = 8661244
47 + 8661197 = 8661244
71 + 8661173 = 8661244
83 + 8661161 = 8661244
107 + 8661137 = 8661244
197 + 8661047 = 8661244

Showing the first eight; more decompositions exist.
