Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642176, here are decompositions:

3 + 8642173 = 8642176
17 + 8642159 = 8642176
29 + 8642147 = 8642176
113 + 8642063 = 8642176
149 + 8642027 = 8642176
173 + 8642003 = 8642176
227 + 8641949 = 8642176
293 + 8641883 = 8642176

Showing the first eight; more decompositions exist.
