Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642202, here are decompositions:

5 + 8642197 = 8642202
13 + 8642189 = 8642202
29 + 8642173 = 8642202
43 + 8642159 = 8642202
61 + 8642141 = 8642202
83 + 8642119 = 8642202
103 + 8642099 = 8642202
139 + 8642063 = 8642202

Showing the first eight; more decompositions exist.
