Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720888, here are decompositions:

79 + 8720809 = 8720888
181 + 8720707 = 8720888
199 + 8720689 = 8720888
271 + 8720617 = 8720888
307 + 8720581 = 8720888
331 + 8720557 = 8720888
409 + 8720479 = 8720888
457 + 8720431 = 8720888

Showing the first eight; more decompositions exist.
