Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720502, here are decompositions:

5 + 8720497 = 8720502
13 + 8720489 = 8720502
19 + 8720483 = 8720502
23 + 8720479 = 8720502
31 + 8720471 = 8720502
71 + 8720431 = 8720502
73 + 8720429 = 8720502
113 + 8720389 = 8720502

Showing the first eight; more decompositions exist.
