Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018912, here are decompositions:

5 + 1018907 = 1018912
23 + 1018889 = 1018912
53 + 1018859 = 1018912
101 + 1018811 = 1018912
149 + 1018763 = 1018912
179 + 1018733 = 1018912
233 + 1018679 = 1018912
239 + 1018673 = 1018912

Showing the first eight; more decompositions exist.
