Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645184, here are decompositions:

5 + 8645179 = 8645184
43 + 8645141 = 8645184
61 + 8645123 = 8645184
71 + 8645113 = 8645184
103 + 8645081 = 8645184
113 + 8645071 = 8645184
131 + 8645053 = 8645184
137 + 8645047 = 8645184

Showing the first eight; more decompositions exist.
