Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642898, here are decompositions:

37 + 8642861 = 8642898
41 + 8642857 = 8642898
59 + 8642839 = 8642898
79 + 8642819 = 8642898
137 + 8642761 = 8642898
151 + 8642747 = 8642898
307 + 8642591 = 8642898
317 + 8642581 = 8642898

Showing the first eight; more decompositions exist.
