Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021994, here are decompositions:

31 + 1021963 = 1021994
97 + 1021897 = 1021994
157 + 1021837 = 1021994
163 + 1021831 = 1021994
241 + 1021753 = 1021994
283 + 1021711 = 1021994
331 + 1021663 = 1021994
367 + 1021627 = 1021994

Showing the first eight; more decompositions exist.
