Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998422, here are decompositions:

3 + 998419 = 998422
11 + 998411 = 998422
23 + 998399 = 998422
41 + 998381 = 998422
149 + 998273 = 998422
179 + 998243 = 998422
311 + 998111 = 998422
353 + 998069 = 998422

Showing the first eight; more decompositions exist.
