Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998578, here are decompositions:

17 + 998561 = 998578
41 + 998537 = 998578
107 + 998471 = 998578
149 + 998429 = 998578
167 + 998411 = 998578
179 + 998399 = 998578
197 + 998381 = 998578
359 + 998219 = 998578

Showing the first eight; more decompositions exist.
