Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008538, here are decompositions:

71 + 1008467 = 1008538
101 + 1008437 = 1008538
131 + 1008407 = 1008538
137 + 1008401 = 1008538
191 + 1008347 = 1008538
281 + 1008257 = 1008538
521 + 1008017 = 1008538
599 + 1007939 = 1008538

Showing the first eight; more decompositions exist.
