Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642146, here are decompositions:

5 + 8642141 = 8642146
47 + 8642099 = 8642146
83 + 8642063 = 8642146
89 + 8642057 = 8642146
113 + 8642033 = 8642146
197 + 8641949 = 8642146
263 + 8641883 = 8642146
449 + 8641697 = 8642146

Showing the first eight; more decompositions exist.
