Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621698, here are decompositions:

5 + 8621693 = 8621698
17 + 8621681 = 8621698
89 + 8621609 = 8621698
269 + 8621429 = 8621698
359 + 8621339 = 8621698
389 + 8621309 = 8621698
461 + 8621237 = 8621698
509 + 8621189 = 8621698

Showing the first eight; more decompositions exist.
