Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993428, here are decompositions:

31 + 993397 = 993428
61 + 993367 = 993428
109 + 993319 = 993428
181 + 993247 = 993428
211 + 993217 = 993428
229 + 993199 = 993428
307 + 993121 = 993428
349 + 993079 = 993428

Showing the first eight; more decompositions exist.
