Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720604, here are decompositions:

7 + 8720597 = 8720604
23 + 8720581 = 8720604
47 + 8720557 = 8720604
71 + 8720533 = 8720604
73 + 8720531 = 8720604
107 + 8720497 = 8720604
127 + 8720477 = 8720604
157 + 8720447 = 8720604

Showing the first eight; more decompositions exist.
