Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969388, here are decompositions:

11 + 969377 = 969388
29 + 969359 = 969388
41 + 969347 = 969388
47 + 969341 = 969388
131 + 969257 = 969388
149 + 969239 = 969388
257 + 969131 = 969388
317 + 969071 = 969388

Showing the first eight; more decompositions exist.
