Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024940, here are decompositions:

19 + 1024921 = 1024940
31 + 1024909 = 1024940
97 + 1024843 = 1024940
157 + 1024783 = 1024940
211 + 1024729 = 1024940
229 + 1024711 = 1024940
271 + 1024669 = 1024940
277 + 1024663 = 1024940

Showing the first eight; more decompositions exist.
