Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646084, here are decompositions:

23 + 8646061 = 8646084
67 + 8646017 = 8646084
103 + 8645981 = 8646084
113 + 8645971 = 8646084
157 + 8645927 = 8646084
197 + 8645887 = 8646084
281 + 8645803 = 8646084
311 + 8645773 = 8646084

Showing the first eight; more decompositions exist.
