Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642196, here are decompositions:

7 + 8642189 = 8642196
23 + 8642173 = 8642196
37 + 8642159 = 8642196
89 + 8642107 = 8642196
97 + 8642099 = 8642196
137 + 8642059 = 8642196
139 + 8642057 = 8642196
163 + 8642033 = 8642196

Showing the first eight; more decompositions exist.
