Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182218, here are decompositions:

17 + 182201 = 182218
41 + 182177 = 182218
59 + 182159 = 182218
89 + 182129 = 182218
107 + 182111 = 182218
191 + 182027 = 182218
251 + 181967 = 182218
347 + 181871 = 182218

Showing the first eight; more decompositions exist.
