Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004428, here are decompositions:

149 + 1004279 = 1004428
311 + 1004117 = 1004428
401 + 1004027 = 1004428
521 + 1003907 = 1004428
587 + 1003841 = 1004428
641 + 1003787 = 1004428
797 + 1003631 = 1004428
809 + 1003619 = 1004428

Showing the first eight; more decompositions exist.
