Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642896, here are decompositions:

47 + 8642849 = 8642896
149 + 8642747 = 8642896
173 + 8642723 = 8642896
263 + 8642633 = 8642896
389 + 8642507 = 8642896
443 + 8642453 = 8642896
467 + 8642429 = 8642896
593 + 8642303 = 8642896

Showing the first eight; more decompositions exist.
