Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642338, here are decompositions:

101 + 8642237 = 8642338
149 + 8642189 = 8642338
179 + 8642159 = 8642338
191 + 8642147 = 8642338
197 + 8642141 = 8642338
227 + 8642111 = 8642338
239 + 8642099 = 8642338
281 + 8642057 = 8642338

Showing the first eight; more decompositions exist.
