Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018942, here are decompositions:

5 + 1018937 = 1018942
11 + 1018931 = 1018942
53 + 1018889 = 1018942
83 + 1018859 = 1018942
131 + 1018811 = 1018942
173 + 1018769 = 1018942
179 + 1018763 = 1018942
233 + 1018709 = 1018942

Showing the first eight; more decompositions exist.
