Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998548, here are decompositions:

11 + 998537 = 998548
137 + 998411 = 998548
149 + 998399 = 998548
167 + 998381 = 998548
311 + 998237 = 998548
347 + 998201 = 998548
401 + 998147 = 998548
431 + 998117 = 998548

Showing the first eight; more decompositions exist.
