Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989388, here are decompositions:

7 + 989381 = 989388
11 + 989377 = 989388
41 + 989347 = 989388
47 + 989341 = 989388
61 + 989327 = 989388
67 + 989321 = 989388
79 + 989309 = 989388
109 + 989279 = 989388

Showing the first eight; more decompositions exist.
