Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998210, here are decompositions:

13 + 998197 = 998210
43 + 998167 = 998210
127 + 998083 = 998210
139 + 998071 = 998210
181 + 998029 = 998210
193 + 998017 = 998210
277 + 997933 = 998210
313 + 997897 = 998210

Showing the first eight; more decompositions exist.
