Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013238, here are decompositions:

11 + 1013227 = 1013238
41 + 1013197 = 1013238
197 + 1013041 = 1013238
229 + 1013009 = 1013238
241 + 1012997 = 1013238
257 + 1012981 = 1013238
271 + 1012967 = 1013238
307 + 1012931 = 1013238

Showing the first eight; more decompositions exist.
