Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021764, here are decompositions:

5 + 1021759 = 1021764
11 + 1021753 = 1021764
17 + 1021747 = 1021764
53 + 1021711 = 1021764
67 + 1021697 = 1021764
101 + 1021663 = 1021764
103 + 1021661 = 1021764
113 + 1021651 = 1021764

Showing the first eight; more decompositions exist.
