Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618750, here are decompositions:

3 + 8618747 = 8618750
13 + 8618737 = 8618750
61 + 8618689 = 8618750
67 + 8618683 = 8618750
157 + 8618593 = 8618750
193 + 8618557 = 8618750
271 + 8618479 = 8618750
307 + 8618443 = 8618750

Showing the first eight; more decompositions exist.
