Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998530, here are decompositions:

3 + 998527 = 998530
17 + 998513 = 998530
59 + 998471 = 998530
101 + 998429 = 998530
107 + 998423 = 998530
131 + 998399 = 998530
149 + 998381 = 998530
257 + 998273 = 998530

Showing the first eight; more decompositions exist.
