Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989312, here are decompositions:

3 + 989309 = 989312
19 + 989293 = 989312
61 + 989251 = 989312
73 + 989239 = 989312
139 + 989173 = 989312
193 + 989119 = 989312
241 + 989071 = 989312
283 + 989029 = 989312

Showing the first eight; more decompositions exist.
