Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642332, here are decompositions:

3 + 8642329 = 8642332
29 + 8642303 = 8642332
173 + 8642159 = 8642332
191 + 8642141 = 8642332
233 + 8642099 = 8642332
269 + 8642063 = 8642332
383 + 8641949 = 8642332
449 + 8641883 = 8642332

Showing the first eight; more decompositions exist.
