Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993620, here are decompositions:

3 + 993617 = 993620
31 + 993589 = 993620
79 + 993541 = 993620
127 + 993493 = 993620
139 + 993481 = 993620
223 + 993397 = 993620
337 + 993283 = 993620
367 + 993253 = 993620

Showing the first eight; more decompositions exist.
