Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630940, here are decompositions:

11 + 8630929 = 8630940
37 + 8630903 = 8630940
41 + 8630899 = 8630940
79 + 8630861 = 8630940
83 + 8630857 = 8630940
89 + 8630851 = 8630940
103 + 8630837 = 8630940
107 + 8630833 = 8630940

Showing the first eight; more decompositions exist.
