Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18058, here are decompositions:

11 + 18047 = 18058
17 + 18041 = 18058
71 + 17987 = 18058
101 + 17957 = 18058
137 + 17921 = 18058
149 + 17909 = 18058
167 + 17891 = 18058
251 + 17807 = 18058

Showing the first eight; more decompositions exist.
