Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020912, here are decompositions:

5 + 1020907 = 1020912
19 + 1020893 = 1020912
31 + 1020881 = 1020912
59 + 1020853 = 1020912
71 + 1020841 = 1020912
73 + 1020839 = 1020912
89 + 1020823 = 1020912
223 + 1020689 = 1020912

Showing the first eight; more decompositions exist.
