Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998426, here are decompositions:

3 + 998423 = 998426
7 + 998419 = 998426
73 + 998353 = 998426
97 + 998329 = 998426
139 + 998287 = 998426
229 + 998197 = 998426
349 + 998077 = 998426
397 + 998029 = 998426

Showing the first eight; more decompositions exist.
