Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049986, here are decompositions:

23 + 1049963 = 1049986
89 + 1049897 = 1049986
137 + 1049849 = 1049986
149 + 1049837 = 1049986
239 + 1049747 = 1049986
269 + 1049717 = 1049986
347 + 1049639 = 1049986
383 + 1049603 = 1049986

Showing the first eight; more decompositions exist.
