Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18148, here are decompositions:

5 + 18143 = 18148
17 + 18131 = 18148
29 + 18119 = 18148
59 + 18089 = 18148
71 + 18077 = 18148
89 + 18059 = 18148
101 + 18047 = 18148
107 + 18041 = 18148

Showing the first eight; more decompositions exist.
