Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720798, here are decompositions:

109 + 8720689 = 8720798
127 + 8720671 = 8720798
181 + 8720617 = 8720798
241 + 8720557 = 8720798
367 + 8720431 = 8720798
409 + 8720389 = 8720798
487 + 8720311 = 8720798
571 + 8720227 = 8720798

Showing the first eight; more decompositions exist.
