Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993990, here are decompositions:

7 + 993983 = 993990
13 + 993977 = 993990
29 + 993961 = 993990
47 + 993943 = 993990
71 + 993919 = 993990
83 + 993907 = 993990
97 + 993893 = 993990
103 + 993887 = 993990

Showing the first eight; more decompositions exist.
