Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643402, here are decompositions:

43 + 8643359 = 8643402
59 + 8643343 = 8643402
179 + 8643223 = 8643402
191 + 8643211 = 8643402
193 + 8643209 = 8643402
269 + 8643133 = 8643402
281 + 8643121 = 8643402
293 + 8643109 = 8643402

Showing the first eight; more decompositions exist.
