Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187284, here are decompositions:

7 + 187277 = 187284
11 + 187273 = 187284
47 + 187237 = 187284
61 + 187223 = 187284
67 + 187217 = 187284
73 + 187211 = 187284
103 + 187181 = 187284
107 + 187177 = 187284

Showing the first eight; more decompositions exist.
