Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184428, here are decompositions:

11 + 184417 = 184428
19 + 184409 = 184428
59 + 184369 = 184428
107 + 184321 = 184428
137 + 184291 = 184428
149 + 184279 = 184428
157 + 184271 = 184428
197 + 184231 = 184428

Showing the first eight; more decompositions exist.
