Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642832, here are decompositions:

13 + 8642819 = 8642832
59 + 8642773 = 8642832
71 + 8642761 = 8642832
109 + 8642723 = 8642832
181 + 8642651 = 8642832
199 + 8642633 = 8642832
241 + 8642591 = 8642832
251 + 8642581 = 8642832

Showing the first eight; more decompositions exist.
