Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021982, here are decompositions:

19 + 1021963 = 1021982
103 + 1021879 = 1021982
151 + 1021831 = 1021982
223 + 1021759 = 1021982
229 + 1021753 = 1021982
271 + 1021711 = 1021982
331 + 1021651 = 1021982
421 + 1021561 = 1021982

Showing the first eight; more decompositions exist.
