Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998488, here are decompositions:

17 + 998471 = 998488
59 + 998429 = 998488
89 + 998399 = 998488
107 + 998381 = 998488
251 + 998237 = 998488
269 + 998219 = 998488
419 + 998069 = 998488
461 + 998027 = 998488

Showing the first eight; more decompositions exist.
