Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998508, here are decompositions:

11 + 998497 = 998508
37 + 998471 = 998508
79 + 998429 = 998508
89 + 998419 = 998508
97 + 998411 = 998508
109 + 998399 = 998508
127 + 998381 = 998508
131 + 998377 = 998508

Showing the first eight; more decompositions exist.
