Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993636, here are decompositions:

19 + 993617 = 993636
47 + 993589 = 993636
79 + 993557 = 993636
109 + 993527 = 993636
157 + 993479 = 993636
199 + 993437 = 993636
229 + 993407 = 993636
239 + 993397 = 993636

Showing the first eight; more decompositions exist.
