Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18124, here are decompositions:

3 + 18121 = 18124
5 + 18119 = 18124
47 + 18077 = 18124
83 + 18041 = 18124
137 + 17987 = 18124
167 + 17957 = 18124
233 + 17891 = 18124
317 + 17807 = 18124

Showing the first eight; more decompositions exist.
