Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705180, here are decompositions:

13 + 8705167 = 8705180
31 + 8705149 = 8705180
103 + 8705077 = 8705180
139 + 8705041 = 8705180
151 + 8705029 = 8705180
199 + 8704981 = 8705180
229 + 8704951 = 8705180
271 + 8704909 = 8705180

Showing the first eight; more decompositions exist.
