Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643282, here are decompositions:

59 + 8643223 = 8643282
71 + 8643211 = 8643282
73 + 8643209 = 8643282
83 + 8643199 = 8643282
101 + 8643181 = 8643282
139 + 8643143 = 8643282
149 + 8643133 = 8643282
173 + 8643109 = 8643282

Showing the first eight; more decompositions exist.
