Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654540, here are decompositions:

19 + 8654521 = 8654540
73 + 8654467 = 8654540
79 + 8654461 = 8654540
109 + 8654431 = 8654540
151 + 8654389 = 8654540
241 + 8654299 = 8654540
283 + 8654257 = 8654540
523 + 8654017 = 8654540

Showing the first eight; more decompositions exist.
