Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018948, here are decompositions:

11 + 1018937 = 1018948
17 + 1018931 = 1018948
41 + 1018907 = 1018948
59 + 1018889 = 1018948
89 + 1018859 = 1018948
131 + 1018817 = 1018948
137 + 1018811 = 1018948
179 + 1018769 = 1018948

Showing the first eight; more decompositions exist.
