Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998562, here are decompositions:

11 + 998551 = 998562
23 + 998539 = 998562
139 + 998423 = 998562
151 + 998411 = 998562
163 + 998399 = 998562
181 + 998381 = 998562
233 + 998329 = 998562
251 + 998311 = 998562

Showing the first eight; more decompositions exist.
