Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982386, here are decompositions:

5 + 982381 = 982386
23 + 982363 = 982386
43 + 982343 = 982386
47 + 982339 = 982386
113 + 982273 = 982386
173 + 982213 = 982386
199 + 982187 = 982386
239 + 982147 = 982386

Showing the first eight; more decompositions exist.
