Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709824, here are decompositions:

3 + 8709821 = 8709824
7 + 8709817 = 8709824
31 + 8709793 = 8709824
43 + 8709781 = 8709824
73 + 8709751 = 8709824
103 + 8709721 = 8709824
127 + 8709697 = 8709824
271 + 8709553 = 8709824

Showing the first eight; more decompositions exist.
