Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998558, here are decompositions:

7 + 998551 = 998558
19 + 998539 = 998558
31 + 998527 = 998558
61 + 998497 = 998558
139 + 998419 = 998558
181 + 998377 = 998558
229 + 998329 = 998558
271 + 998287 = 998558

Showing the first eight; more decompositions exist.
