Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705018, here are decompositions:

37 + 8704981 = 8705018
67 + 8704951 = 8705018
97 + 8704921 = 8705018
109 + 8704909 = 8705018
181 + 8704837 = 8705018
241 + 8704777 = 8705018
307 + 8704711 = 8705018
331 + 8704687 = 8705018

Showing the first eight; more decompositions exist.
