Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618730, here are decompositions:

31 + 8618699 = 8618730
41 + 8618689 = 8618730
47 + 8618683 = 8618730
137 + 8618593 = 8618730
139 + 8618591 = 8618730
149 + 8618581 = 8618730
163 + 8618567 = 8618730
173 + 8618557 = 8618730

Showing the first eight; more decompositions exist.
