Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749824, here are decompositions:

7 + 8749817 = 8749824
11 + 8749813 = 8749824
37 + 8749787 = 8749824
53 + 8749771 = 8749824
71 + 8749753 = 8749824
73 + 8749751 = 8749824
173 + 8749651 = 8749824
197 + 8749627 = 8749824

Showing the first eight; more decompositions exist.
