Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005238, here are decompositions:

29 + 1005209 = 1005238
107 + 1005131 = 1005238
131 + 1005107 = 1005238
137 + 1005101 = 1005238
167 + 1005071 = 1005238
197 + 1005041 = 1005238
251 + 1004987 = 1005238
257 + 1004981 = 1005238

Showing the first eight; more decompositions exist.
