Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720526, here are decompositions:

13 + 8720513 = 8720526
29 + 8720497 = 8720526
37 + 8720489 = 8720526
43 + 8720483 = 8720526
47 + 8720479 = 8720526
79 + 8720447 = 8720526
97 + 8720429 = 8720526
109 + 8720417 = 8720526

Showing the first eight; more decompositions exist.
