Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646090, here are decompositions:

29 + 8646061 = 8646090
31 + 8646059 = 8646090
73 + 8646017 = 8646090
109 + 8645981 = 8646090
149 + 8645941 = 8646090
163 + 8645927 = 8646090
191 + 8645899 = 8646090
227 + 8645863 = 8646090

Showing the first eight; more decompositions exist.
