Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720984, here are decompositions:

7 + 8720977 = 8720984
31 + 8720953 = 8720984
37 + 8720947 = 8720984
43 + 8720941 = 8720984
73 + 8720911 = 8720984
211 + 8720773 = 8720984
271 + 8720713 = 8720984
277 + 8720707 = 8720984

Showing the first eight; more decompositions exist.
