Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989168, here are decompositions:

97 + 989071 = 989168
109 + 989059 = 989168
139 + 989029 = 989168
157 + 989011 = 989168
307 + 988861 = 989168
331 + 988837 = 989168
379 + 988789 = 989168
409 + 988759 = 989168

Showing the first eight; more decompositions exist.
