Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640284, here are decompositions:

43 + 8640241 = 8640284
73 + 8640211 = 8640284
97 + 8640187 = 8640284
151 + 8640133 = 8640284
271 + 8640013 = 8640284
283 + 8640001 = 8640284
307 + 8639977 = 8640284
421 + 8639863 = 8640284

Showing the first eight; more decompositions exist.
