Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17838, here are decompositions:

11 + 17827 = 17838
31 + 17807 = 17838
47 + 17791 = 17838
89 + 17749 = 17838
101 + 17737 = 17838
109 + 17729 = 17838
131 + 17707 = 17838
157 + 17681 = 17838

Showing the first eight; more decompositions exist.
