Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998438, here are decompositions:

19 + 998419 = 998438
61 + 998377 = 998438
109 + 998329 = 998438
127 + 998311 = 998438
151 + 998287 = 998438
157 + 998281 = 998438
241 + 998197 = 998438
271 + 998167 = 998438

Showing the first eight; more decompositions exist.
