Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18120, here are decompositions:

23 + 18097 = 18120
31 + 18089 = 18120
43 + 18077 = 18120
59 + 18061 = 18120
61 + 18059 = 18120
71 + 18049 = 18120
73 + 18047 = 18120
79 + 18041 = 18120

Showing the first eight; more decompositions exist.
