Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720508, here are decompositions:

11 + 8720497 = 8720508
19 + 8720489 = 8720508
29 + 8720479 = 8720508
31 + 8720477 = 8720508
37 + 8720471 = 8720508
61 + 8720447 = 8720508
79 + 8720429 = 8720508
101 + 8720407 = 8720508

Showing the first eight; more decompositions exist.
