Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646844, here are decompositions:

23 + 8646821 = 8646844
137 + 8646707 = 8646844
263 + 8646581 = 8646844
347 + 8646497 = 8646844
443 + 8646401 = 8646844
467 + 8646377 = 8646844
587 + 8646257 = 8646844
617 + 8646227 = 8646844

Showing the first eight; more decompositions exist.
