Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187350, here are decompositions:

11 + 187339 = 187350
13 + 187337 = 187350
47 + 187303 = 187350
73 + 187277 = 187350
113 + 187237 = 187350
127 + 187223 = 187350
131 + 187219 = 187350
139 + 187211 = 187350

Showing the first eight; more decompositions exist.
