Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989420, here are decompositions:

43 + 989377 = 989420
67 + 989353 = 989420
73 + 989347 = 989420
79 + 989341 = 989420
97 + 989323 = 989420
127 + 989293 = 989420
181 + 989239 = 989420
349 + 989071 = 989420

Showing the first eight; more decompositions exist.
