Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18836, here are decompositions:

43 + 18793 = 18836
79 + 18757 = 18836
157 + 18679 = 18836
199 + 18637 = 18836
283 + 18553 = 18836
313 + 18523 = 18836
379 + 18457 = 18836
397 + 18439 = 18836

Showing the first eight; more decompositions exist.
