Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738540, here are decompositions:

7 + 8738533 = 8738540
67 + 8738473 = 8738540
103 + 8738437 = 8738540
157 + 8738383 = 8738540
163 + 8738377 = 8738540
241 + 8738299 = 8738540
277 + 8738263 = 8738540
313 + 8738227 = 8738540

Showing the first eight; more decompositions exist.
