Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705258, here are decompositions:

109 + 8705149 = 8705258
181 + 8705077 = 8705258
229 + 8705029 = 8705258
277 + 8704981 = 8705258
307 + 8704951 = 8705258
337 + 8704921 = 8705258
349 + 8704909 = 8705258
421 + 8704837 = 8705258

Showing the first eight; more decompositions exist.
