Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998090, here are decompositions:

7 + 998083 = 998090
13 + 998077 = 998090
19 + 998071 = 998090
61 + 998029 = 998090
73 + 998017 = 998090
127 + 997963 = 998090
157 + 997933 = 998090
193 + 997897 = 998090

Showing the first eight; more decompositions exist.
