Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18202, here are decompositions:

3 + 18199 = 18202
11 + 18191 = 18202
53 + 18149 = 18202
59 + 18143 = 18202
71 + 18131 = 18202
83 + 18119 = 18202
113 + 18089 = 18202
263 + 17939 = 18202

Showing the first eight; more decompositions exist.
