Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642350, here are decompositions:

47 + 8642303 = 8642350
113 + 8642237 = 8642350
191 + 8642159 = 8642350
239 + 8642111 = 8642350
251 + 8642099 = 8642350
293 + 8642057 = 8642350
317 + 8642033 = 8642350
347 + 8642003 = 8642350

Showing the first eight; more decompositions exist.
