Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648942, here are decompositions:

13 + 8648929 = 8648942
19 + 8648923 = 8648942
61 + 8648881 = 8648942
79 + 8648863 = 8648942
103 + 8648839 = 8648942
109 + 8648833 = 8648942
151 + 8648791 = 8648942
163 + 8648779 = 8648942

Showing the first eight; more decompositions exist.
