Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020940, here are decompositions:

47 + 1020893 = 1020940
59 + 1020881 = 1020940
101 + 1020839 = 1020940
113 + 1020827 = 1020940
197 + 1020743 = 1020940
233 + 1020707 = 1020940
251 + 1020689 = 1020940
257 + 1020683 = 1020940

Showing the first eight; more decompositions exist.
