Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993978, here are decompositions:

17 + 993961 = 993978
59 + 993919 = 993978
71 + 993907 = 993978
109 + 993869 = 993978
127 + 993851 = 993978
137 + 993841 = 993978
151 + 993827 = 993978
157 + 993821 = 993978

Showing the first eight; more decompositions exist.
