Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187318, here are decompositions:

41 + 187277 = 187318
101 + 187217 = 187318
107 + 187211 = 187318
137 + 187181 = 187318
179 + 187139 = 187318
191 + 187127 = 187318
227 + 187091 = 187318
251 + 187067 = 187318

Showing the first eight; more decompositions exist.
