Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618670, here are decompositions:

31 + 8618639 = 8618670
79 + 8618591 = 8618670
89 + 8618581 = 8618670
103 + 8618567 = 8618670
113 + 8618557 = 8618670
191 + 8618479 = 8618670
227 + 8618443 = 8618670
241 + 8618429 = 8618670

Showing the first eight; more decompositions exist.
