Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645848, here are decompositions:

59 + 8645789 = 8645848
89 + 8645759 = 8645848
179 + 8645669 = 8645848
191 + 8645657 = 8645848
251 + 8645597 = 8645848
269 + 8645579 = 8645848
467 + 8645381 = 8645848
521 + 8645327 = 8645848

Showing the first eight; more decompositions exist.
