Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051198, here are decompositions:

17 + 1051181 = 1051198
41 + 1051157 = 1051198
47 + 1051151 = 1051198
59 + 1051139 = 1051198
179 + 1051019 = 1051198
191 + 1051007 = 1051198
311 + 1050887 = 1051198
347 + 1050851 = 1051198

Showing the first eight; more decompositions exist.
