Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008278, here are decompositions:

31 + 1008247 = 1008278
79 + 1008199 = 1008278
97 + 1008181 = 1008278
241 + 1008037 = 1008278
277 + 1008001 = 1008278
307 + 1007971 = 1008278
421 + 1007857 = 1008278
547 + 1007731 = 1008278

Showing the first eight; more decompositions exist.
