Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642824, here are decompositions:

5 + 8642819 = 8642824
101 + 8642723 = 8642824
173 + 8642651 = 8642824
191 + 8642633 = 8642824
233 + 8642591 = 8642824
257 + 8642567 = 8642824
317 + 8642507 = 8642824
521 + 8642303 = 8642824

Showing the first eight; more decompositions exist.
