Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642082, here are decompositions:

5 + 8642077 = 8642082
19 + 8642063 = 8642082
23 + 8642059 = 8642082
79 + 8642003 = 8642082
173 + 8641909 = 8642082
191 + 8641891 = 8642082
199 + 8641883 = 8642082
263 + 8641819 = 8642082

Showing the first eight; more decompositions exist.
