Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020198, here are decompositions:

41 + 1020157 = 1020198
61 + 1020137 = 1020198
89 + 1020109 = 1020198
97 + 1020101 = 1020198
139 + 1020059 = 1020198
149 + 1020049 = 1020198
191 + 1020007 = 1020198
197 + 1020001 = 1020198

Showing the first eight; more decompositions exist.
