Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187356, here are decompositions:

7 + 187349 = 187356
17 + 187339 = 187356
19 + 187337 = 187356
53 + 187303 = 187356
79 + 187277 = 187356
83 + 187273 = 187356
137 + 187219 = 187356
139 + 187217 = 187356

Showing the first eight; more decompositions exist.
