Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642262, here are decompositions:

73 + 8642189 = 8642262
89 + 8642173 = 8642262
103 + 8642159 = 8642262
151 + 8642111 = 8642262
163 + 8642099 = 8642262
199 + 8642063 = 8642262
229 + 8642033 = 8642262
271 + 8641991 = 8642262

Showing the first eight; more decompositions exist.
