Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993278, here are decompositions:

31 + 993247 = 993278
37 + 993241 = 993278
61 + 993217 = 993278
67 + 993211 = 993278
79 + 993199 = 993278
109 + 993169 = 993278
157 + 993121 = 993278
199 + 993079 = 993278

Showing the first eight; more decompositions exist.
