Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618540, here are decompositions:

61 + 8618479 = 8618540
97 + 8618443 = 8618540
127 + 8618413 = 8618540
163 + 8618377 = 8618540
211 + 8618329 = 8618540
223 + 8618317 = 8618540
283 + 8618257 = 8618540
367 + 8618173 = 8618540

Showing the first eight; more decompositions exist.
