Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021968, here are decompositions:

5 + 1021963 = 1021968
7 + 1021961 = 1021968
61 + 1021907 = 1021968
71 + 1021897 = 1021968
89 + 1021879 = 1021968
107 + 1021861 = 1021968
131 + 1021837 = 1021968
137 + 1021831 = 1021968

Showing the first eight; more decompositions exist.
