Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627984, here are decompositions:

7 + 8627977 = 8627984
31 + 8627953 = 8627984
37 + 8627947 = 8627984
73 + 8627911 = 8627984
151 + 8627833 = 8627984
271 + 8627713 = 8627984
283 + 8627701 = 8627984
367 + 8627617 = 8627984

Showing the first eight; more decompositions exist.
