Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642932, here are decompositions:

5 + 8642927 = 8642932
29 + 8642903 = 8642932
71 + 8642861 = 8642932
83 + 8642849 = 8642932
113 + 8642819 = 8642932
281 + 8642651 = 8642932
443 + 8642489 = 8642932
479 + 8642453 = 8642932

Showing the first eight; more decompositions exist.
