Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18038, here are decompositions:

61 + 17977 = 18038
67 + 17971 = 18038
79 + 17959 = 18038
109 + 17929 = 18038
127 + 17911 = 18038
157 + 17881 = 18038
199 + 17839 = 18038
211 + 17827 = 18038

Showing the first eight; more decompositions exist.
