Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972388, here are decompositions:

41 + 972347 = 972388
59 + 972329 = 972388
167 + 972221 = 972388
191 + 972197 = 972388
227 + 972161 = 972388
251 + 972137 = 972388
257 + 972131 = 972388
269 + 972119 = 972388

Showing the first eight; more decompositions exist.
