Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641290, here are decompositions:

17 + 8641273 = 8641290
41 + 8641249 = 8641290
43 + 8641247 = 8641290
59 + 8641231 = 8641290
79 + 8641211 = 8641290
103 + 8641187 = 8641290
157 + 8641133 = 8641290
193 + 8641097 = 8641290

Showing the first eight; more decompositions exist.
