Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993900, here are decompositions:

7 + 993893 = 993900
13 + 993887 = 993900
31 + 993869 = 993900
59 + 993841 = 993900
73 + 993827 = 993900
79 + 993821 = 993900
107 + 993793 = 993900
137 + 993763 = 993900

Showing the first eight; more decompositions exist.
