Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008912, here are decompositions:

11 + 1008901 = 1008912
41 + 1008871 = 1008912
53 + 1008859 = 1008912
59 + 1008853 = 1008912
61 + 1008851 = 1008912
83 + 1008829 = 1008912
103 + 1008809 = 1008912
131 + 1008781 = 1008912

Showing the first eight; more decompositions exist.
