Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642328, here are decompositions:

47 + 8642281 = 8642328
131 + 8642197 = 8642328
139 + 8642189 = 8642328
181 + 8642147 = 8642328
229 + 8642099 = 8642328
251 + 8642077 = 8642328
269 + 8642059 = 8642328
271 + 8642057 = 8642328

Showing the first eight; more decompositions exist.
