Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998390, here are decompositions:

13 + 998377 = 998390
37 + 998353 = 998390
61 + 998329 = 998390
79 + 998311 = 998390
103 + 998287 = 998390
109 + 998281 = 998390
193 + 998197 = 998390
223 + 998167 = 998390

Showing the first eight; more decompositions exist.
