Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152388, here are decompositions:

7 + 152381 = 152388
11 + 152377 = 152388
101 + 152287 = 152388
139 + 152249 = 152388
149 + 152239 = 152388
157 + 152231 = 152388
191 + 152197 = 152388
199 + 152189 = 152388

Showing the first eight; more decompositions exist.
