Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630942, here are decompositions:

13 + 8630929 = 8630942
43 + 8630899 = 8630942
109 + 8630833 = 8630942
163 + 8630779 = 8630942
193 + 8630749 = 8630942
349 + 8630593 = 8630942
499 + 8630443 = 8630942
631 + 8630311 = 8630942

Showing the first eight; more decompositions exist.
