Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720586, here are decompositions:

5 + 8720581 = 8720586
29 + 8720557 = 8720586
53 + 8720533 = 8720586
73 + 8720513 = 8720586
89 + 8720497 = 8720586
97 + 8720489 = 8720586
103 + 8720483 = 8720586
107 + 8720479 = 8720586

Showing the first eight; more decompositions exist.
