Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528604, here are decompositions:

113 + 528491 = 528604
191 + 528413 = 528604
467 + 528137 = 528604
563 + 528041 = 528604
617 + 527987 = 528604
683 + 527921 = 528604
761 + 527843 = 528604
863 + 527741 = 528604

Showing the first eight; more decompositions exist.
