Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18174, here are decompositions:

5 + 18169 = 18174
31 + 18143 = 18174
41 + 18133 = 18174
43 + 18131 = 18174
47 + 18127 = 18174
53 + 18121 = 18174
97 + 18077 = 18174
113 + 18061 = 18174

Showing the first eight; more decompositions exist.
