Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012198, here are decompositions:

101 + 1012097 = 1012198
149 + 1012049 = 1012198
167 + 1012031 = 1012198
191 + 1012007 = 1012198
251 + 1011947 = 1012198
281 + 1011917 = 1012198
401 + 1011797 = 1012198
419 + 1011779 = 1012198

Showing the first eight; more decompositions exist.
