Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643482, here are decompositions:

73 + 8643409 = 8643482
139 + 8643343 = 8643482
271 + 8643211 = 8643482
283 + 8643199 = 8643482
349 + 8643133 = 8643482
373 + 8643109 = 8643482
571 + 8642911 = 8643482
619 + 8642863 = 8643482

Showing the first eight; more decompositions exist.
