Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989386, here are decompositions:

5 + 989381 = 989386
59 + 989327 = 989386
107 + 989279 = 989386
137 + 989249 = 989386
263 + 989123 = 989386
449 + 988937 = 989386
509 + 988877 = 989386
557 + 988829 = 989386

Showing the first eight; more decompositions exist.
