Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616260, here are decompositions:

13 + 8616247 = 8616260
19 + 8616241 = 8616260
43 + 8616217 = 8616260
61 + 8616199 = 8616260
73 + 8616187 = 8616260
109 + 8616151 = 8616260
223 + 8616037 = 8616260
241 + 8616019 = 8616260

Showing the first eight; more decompositions exist.
