Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019208, here are decompositions:

11 + 1019197 = 1019208
31 + 1019177 = 1019208
79 + 1019129 = 1019208
89 + 1019119 = 1019208
131 + 1019077 = 1019208
137 + 1019071 = 1019208
139 + 1019069 = 1019208
149 + 1019059 = 1019208

Showing the first eight; more decompositions exist.
