Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621546, here are decompositions:

67 + 8621479 = 8621546
79 + 8621467 = 8621546
103 + 8621443 = 8621546
337 + 8621209 = 8621546
457 + 8621089 = 8621546
463 + 8621083 = 8621546
499 + 8621047 = 8621546
673 + 8620873 = 8621546

Showing the first eight; more decompositions exist.
