Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026940, here are decompositions:

23 + 1026917 = 1026940
29 + 1026911 = 1026940
41 + 1026899 = 1026940
53 + 1026887 = 1026940
107 + 1026833 = 1026940
149 + 1026791 = 1026940
179 + 1026761 = 1026940
263 + 1026677 = 1026940

Showing the first eight; more decompositions exist.
