Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18250, here are decompositions:

17 + 18233 = 18250
59 + 18191 = 18250
101 + 18149 = 18250
107 + 18143 = 18250
131 + 18119 = 18250
173 + 18077 = 18250
191 + 18059 = 18250
263 + 17987 = 18250

Showing the first eight; more decompositions exist.
