Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989406, here are decompositions:

29 + 989377 = 989406
53 + 989353 = 989406
59 + 989347 = 989406
79 + 989327 = 989406
83 + 989323 = 989406
97 + 989309 = 989406
113 + 989293 = 989406
127 + 989279 = 989406

Showing the first eight; more decompositions exist.
