Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042198, here are decompositions:

5 + 1042193 = 1042198
11 + 1042187 = 1042198
89 + 1042109 = 1042198
107 + 1042091 = 1042198
197 + 1042001 = 1042198
419 + 1041779 = 1042198
461 + 1041737 = 1042198
467 + 1041731 = 1042198

Showing the first eight; more decompositions exist.
