Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019938, here are decompositions:

11 + 1019927 = 1019938
89 + 1019849 = 1019938
137 + 1019801 = 1019938
167 + 1019771 = 1019938
191 + 1019747 = 1019938
197 + 1019741 = 1019938
239 + 1019699 = 1019938
251 + 1019687 = 1019938

Showing the first eight; more decompositions exist.
