Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998030, here are decompositions:

3 + 998027 = 998030
13 + 998017 = 998030
67 + 997963 = 998030
97 + 997933 = 998030
139 + 997891 = 998030
151 + 997879 = 998030
223 + 997807 = 998030
331 + 997699 = 998030

Showing the first eight; more decompositions exist.
