Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18046, here are decompositions:

3 + 18043 = 18046
5 + 18041 = 18046
59 + 17987 = 18046
89 + 17957 = 18046
107 + 17939 = 18046
137 + 17909 = 18046
239 + 17807 = 18046
257 + 17789 = 18046

Showing the first eight; more decompositions exist.
