Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004638, here are decompositions:

71 + 1004567 = 1004638
101 + 1004537 = 1004638
137 + 1004501 = 1004638
197 + 1004441 = 1004638
359 + 1004279 = 1004638
521 + 1004117 = 1004638
797 + 1003841 = 1004638
821 + 1003817 = 1004638

Showing the first eight; more decompositions exist.
