Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019198, here are decompositions:

79 + 1019119 = 1019198
127 + 1019071 = 1019198
139 + 1019059 = 1019198
199 + 1018999 = 1019198
211 + 1018987 = 1019198
241 + 1018957 = 1019198
409 + 1018789 = 1019198
421 + 1018777 = 1019198

Showing the first eight; more decompositions exist.
