Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998608, here are decompositions:

47 + 998561 = 998608
71 + 998537 = 998608
137 + 998471 = 998608
179 + 998429 = 998608
197 + 998411 = 998608
227 + 998381 = 998608
389 + 998219 = 998608
461 + 998147 = 998608

Showing the first eight; more decompositions exist.
