Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993996, here are decompositions:

13 + 993983 = 993996
19 + 993977 = 993996
53 + 993943 = 993996
83 + 993913 = 993996
89 + 993907 = 993996
103 + 993893 = 993996
109 + 993887 = 993996
127 + 993869 = 993996

Showing the first eight; more decompositions exist.
