Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620984, here are decompositions:

11 + 8620973 = 8620984
41 + 8620943 = 8620984
137 + 8620847 = 8620984
227 + 8620757 = 8620984
257 + 8620727 = 8620984
263 + 8620721 = 8620984
293 + 8620691 = 8620984
311 + 8620673 = 8620984

Showing the first eight; more decompositions exist.
