Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992988, here are decompositions:

5 + 992983 = 992988
41 + 992947 = 992988
47 + 992941 = 992988
71 + 992917 = 992988
97 + 992891 = 992988
127 + 992861 = 992988
131 + 992857 = 992988
179 + 992809 = 992988

Showing the first eight; more decompositions exist.
