Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002940, here are decompositions:

11 + 1002929 = 1002940
23 + 1002917 = 1002940
41 + 1002899 = 1002940
47 + 1002893 = 1002940
53 + 1002887 = 1002940
83 + 1002857 = 1002940
89 + 1002851 = 1002940
131 + 1002809 = 1002940

Showing the first eight; more decompositions exist.
