Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642292, here are decompositions:

11 + 8642281 = 8642292
103 + 8642189 = 8642292
151 + 8642141 = 8642292
173 + 8642119 = 8642292
181 + 8642111 = 8642292
193 + 8642099 = 8642292
229 + 8642063 = 8642292
233 + 8642059 = 8642292

Showing the first eight; more decompositions exist.
