Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993640, here are decompositions:

23 + 993617 = 993640
29 + 993611 = 993640
83 + 993557 = 993640
113 + 993527 = 993640
173 + 993467 = 993640
233 + 993407 = 993640
239 + 993401 = 993640
317 + 993323 = 993640

Showing the first eight; more decompositions exist.
