Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668382, here are decompositions:

3 + 8668379 = 8668382
13 + 8668369 = 8668382
103 + 8668279 = 8668382
109 + 8668273 = 8668382
181 + 8668201 = 8668382
241 + 8668141 = 8668382
271 + 8668111 = 8668382
409 + 8667973 = 8668382

Showing the first eight; more decompositions exist.
