Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185418, here are decompositions:

17 + 185401 = 185418
47 + 185371 = 185418
59 + 185359 = 185418
109 + 185309 = 185418
127 + 185291 = 185418
151 + 185267 = 185418
197 + 185221 = 185418
229 + 185189 = 185418

Showing the first eight; more decompositions exist.
