Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18088, here are decompositions:

11 + 18077 = 18088
29 + 18059 = 18088
41 + 18047 = 18088
47 + 18041 = 18088
101 + 17987 = 18088
107 + 17981 = 18088
131 + 17957 = 18088
149 + 17939 = 18088

Showing the first eight; more decompositions exist.
