Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018828, here are decompositions:

11 + 1018817 = 1018828
17 + 1018811 = 1018828
59 + 1018769 = 1018828
131 + 1018697 = 1018828
149 + 1018679 = 1018828
179 + 1018649 = 1018828
269 + 1018559 = 1018828
389 + 1018439 = 1018828

Showing the first eight; more decompositions exist.
