Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648990, here are decompositions:

37 + 8648953 = 8648990
61 + 8648929 = 8648990
67 + 8648923 = 8648990
109 + 8648881 = 8648990
127 + 8648863 = 8648990
151 + 8648839 = 8648990
157 + 8648833 = 8648990
193 + 8648797 = 8648990

Showing the first eight; more decompositions exist.
