Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18102, here are decompositions:

5 + 18097 = 18102
13 + 18089 = 18102
41 + 18061 = 18102
43 + 18059 = 18102
53 + 18049 = 18102
59 + 18043 = 18102
61 + 18041 = 18102
89 + 18013 = 18102

Showing the first eight; more decompositions exist.
