Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618516, here are decompositions:

37 + 8618479 = 8618516
73 + 8618443 = 8618516
103 + 8618413 = 8618516
139 + 8618377 = 8618516
199 + 8618317 = 8618516
223 + 8618293 = 8618516
229 + 8618287 = 8618516
367 + 8618149 = 8618516

Showing the first eight; more decompositions exist.
