Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998406, here are decompositions:

7 + 998399 = 998406
29 + 998377 = 998406
53 + 998353 = 998406
163 + 998243 = 998406
193 + 998213 = 998406
239 + 998167 = 998406
337 + 998069 = 998406
379 + 998027 = 998406

Showing the first eight; more decompositions exist.
