Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643292, here are decompositions:

5 + 8643287 = 8643292
11 + 8643281 = 8643292
83 + 8643209 = 8643292
149 + 8643143 = 8643292
233 + 8643059 = 8643292
239 + 8643053 = 8643292
269 + 8643023 = 8643292
353 + 8642939 = 8643292

Showing the first eight; more decompositions exist.
