Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187288, here are decompositions:

11 + 187277 = 187288
71 + 187217 = 187288
107 + 187181 = 187288
149 + 187139 = 187288
197 + 187091 = 187288
239 + 187049 = 187288
419 + 186869 = 187288
587 + 186701 = 187288

Showing the first eight; more decompositions exist.
