Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183428, here are decompositions:

31 + 183397 = 183428
67 + 183361 = 183428
79 + 183349 = 183428
109 + 183319 = 183428
127 + 183301 = 183428
139 + 183289 = 183428
181 + 183247 = 183428
277 + 183151 = 183428

Showing the first eight; more decompositions exist.
