Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184218, here are decompositions:

7 + 184211 = 184218
19 + 184199 = 184218
29 + 184189 = 184218
31 + 184187 = 184218
37 + 184181 = 184218
61 + 184157 = 184218
101 + 184117 = 184218
107 + 184111 = 184218

Showing the first eight; more decompositions exist.
