Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618460, here are decompositions:

17 + 8618443 = 8618460
31 + 8618429 = 8618460
47 + 8618413 = 8618460
73 + 8618387 = 8618460
83 + 8618377 = 8618460
131 + 8618329 = 8618460
163 + 8618297 = 8618460
167 + 8618293 = 8618460

Showing the first eight; more decompositions exist.
