Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18834, here are decompositions:

31 + 18803 = 18834
37 + 18797 = 18834
41 + 18793 = 18834
47 + 18787 = 18834
61 + 18773 = 18834
103 + 18731 = 18834
163 + 18671 = 18834
173 + 18661 = 18834

Showing the first eight; more decompositions exist.
