Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008238, here are decompositions:

5 + 1008233 = 1008238
29 + 1008209 = 1008238
107 + 1008131 = 1008238
137 + 1008101 = 1008238
197 + 1008041 = 1008238
281 + 1007957 = 1008238
317 + 1007921 = 1008238
347 + 1007891 = 1008238

Showing the first eight; more decompositions exist.
