Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642926, here are decompositions:

23 + 8642903 = 8642926
29 + 8642897 = 8642926
107 + 8642819 = 8642926
179 + 8642747 = 8642926
293 + 8642633 = 8642926
359 + 8642567 = 8642926
419 + 8642507 = 8642926
827 + 8642099 = 8642926

Showing the first eight; more decompositions exist.
