Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618664, here are decompositions:

71 + 8618593 = 8618664
73 + 8618591 = 8618664
83 + 8618581 = 8618664
97 + 8618567 = 8618664
107 + 8618557 = 8618664
163 + 8618501 = 8618664
181 + 8618483 = 8618664
251 + 8618413 = 8618664

Showing the first eight; more decompositions exist.
