Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187558, here are decompositions:

11 + 187547 = 187558
89 + 187469 = 187558
149 + 187409 = 187558
179 + 187379 = 187558
191 + 187367 = 187558
197 + 187361 = 187558
281 + 187277 = 187558
347 + 187211 = 187558

Showing the first eight; more decompositions exist.
