Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989278, here are decompositions:

29 + 989249 = 989278
47 + 989231 = 989278
107 + 989171 = 989278
179 + 989099 = 989278
197 + 989081 = 989278
401 + 988877 = 989278
419 + 988859 = 989278
449 + 988829 = 989278

Showing the first eight; more decompositions exist.
