Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618498, here are decompositions:

19 + 8618479 = 8618498
181 + 8618317 = 8618498
211 + 8618287 = 8618498
241 + 8618257 = 8618498
277 + 8618221 = 8618498
349 + 8618149 = 8618498
367 + 8618131 = 8618498
379 + 8618119 = 8618498

Showing the first eight; more decompositions exist.
