Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736720, here are decompositions:

17 + 8736703 = 8736720
19 + 8736701 = 8736720
37 + 8736683 = 8736720
53 + 8736667 = 8736720
61 + 8736659 = 8736720
67 + 8736653 = 8736720
73 + 8736647 = 8736720
89 + 8736631 = 8736720

Showing the first eight; more decompositions exist.
