Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989148, here are decompositions:

29 + 989119 = 989148
67 + 989081 = 989148
89 + 989059 = 989148
137 + 989011 = 989148
197 + 988951 = 989148
211 + 988937 = 989148
239 + 988909 = 989148
271 + 988877 = 989148

Showing the first eight; more decompositions exist.
