Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993500, here are decompositions:

7 + 993493 = 993500
19 + 993481 = 993500
103 + 993397 = 993500
181 + 993319 = 993500
283 + 993217 = 993500
331 + 993169 = 993500
379 + 993121 = 993500
397 + 993103 = 993500

Showing the first eight; more decompositions exist.
