Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187252, here are decompositions:

29 + 187223 = 187252
41 + 187211 = 187252
59 + 187193 = 187252
71 + 187181 = 187252
89 + 187163 = 187252
113 + 187139 = 187252
179 + 187073 = 187252
293 + 186959 = 187252

Showing the first eight; more decompositions exist.
