Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642776, here are decompositions:

3 + 8642773 = 8642776
29 + 8642747 = 8642776
53 + 8642723 = 8642776
257 + 8642519 = 8642776
269 + 8642507 = 8642776
347 + 8642429 = 8642776
587 + 8642189 = 8642776
617 + 8642159 = 8642776

Showing the first eight; more decompositions exist.
