Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705540, here are decompositions:

13 + 8705527 = 8705540
73 + 8705467 = 8705540
79 + 8705461 = 8705540
97 + 8705443 = 8705540
157 + 8705383 = 8705540
229 + 8705311 = 8705540
241 + 8705299 = 8705540
271 + 8705269 = 8705540

Showing the first eight; more decompositions exist.
