Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749724, here are decompositions:

73 + 8749651 = 8749724
97 + 8749627 = 8749724
307 + 8749417 = 8749724
367 + 8749357 = 8749724
733 + 8748991 = 8749724
751 + 8748973 = 8749724
877 + 8748847 = 8749724
883 + 8748841 = 8749724

Showing the first eight; more decompositions exist.
