Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187204, here are decompositions:

11 + 187193 = 187204
23 + 187181 = 187204
41 + 187163 = 187204
71 + 187133 = 187204
113 + 187091 = 187204
131 + 187073 = 187204
137 + 187067 = 187204
257 + 186947 = 187204

Showing the first eight; more decompositions exist.
