Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187248, here are decompositions:

11 + 187237 = 187248
29 + 187219 = 187248
31 + 187217 = 187248
37 + 187211 = 187248
59 + 187189 = 187248
67 + 187181 = 187248
71 + 187177 = 187248
107 + 187141 = 187248

Showing the first eight; more decompositions exist.
