Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618510, here are decompositions:

31 + 8618479 = 8618510
67 + 8618443 = 8618510
97 + 8618413 = 8618510
181 + 8618329 = 8618510
193 + 8618317 = 8618510
223 + 8618287 = 8618510
337 + 8618173 = 8618510
379 + 8618131 = 8618510

Showing the first eight; more decompositions exist.
