Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018960, here are decompositions:

3 + 1018957 = 1018960
11 + 1018949 = 1018960
23 + 1018937 = 1018960
29 + 1018931 = 1018960
53 + 1018907 = 1018960
71 + 1018889 = 1018960
101 + 1018859 = 1018960
149 + 1018811 = 1018960

Showing the first eight; more decompositions exist.
