Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621384, here are decompositions:

7 + 8621377 = 8621384
103 + 8621281 = 8621384
241 + 8621143 = 8621384
283 + 8621101 = 8621384
307 + 8621077 = 8621384
337 + 8621047 = 8621384
367 + 8621017 = 8621384
433 + 8620951 = 8621384

Showing the first eight; more decompositions exist.
