Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998560, here are decompositions:

23 + 998537 = 998560
47 + 998513 = 998560
89 + 998471 = 998560
131 + 998429 = 998560
137 + 998423 = 998560
149 + 998411 = 998560
179 + 998381 = 998560
317 + 998243 = 998560

Showing the first eight; more decompositions exist.
