Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682442, here are decompositions:

5 + 8682437 = 8682442
29 + 8682413 = 8682442
173 + 8682269 = 8682442
191 + 8682251 = 8682442
233 + 8682209 = 8682442
239 + 8682203 = 8682442
401 + 8682041 = 8682442
443 + 8681999 = 8682442

Showing the first eight; more decompositions exist.
