Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021814, here are decompositions:

7 + 1021807 = 1021814
37 + 1021777 = 1021814
61 + 1021753 = 1021814
67 + 1021747 = 1021814
103 + 1021711 = 1021814
151 + 1021663 = 1021814
163 + 1021651 = 1021814
193 + 1021621 = 1021814

Showing the first eight; more decompositions exist.
