Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998270, here are decompositions:

73 + 998197 = 998270
103 + 998167 = 998270
109 + 998161 = 998270
193 + 998077 = 998270
199 + 998071 = 998270
241 + 998029 = 998270
307 + 997963 = 998270
337 + 997933 = 998270

Showing the first eight; more decompositions exist.
