Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662540, here are decompositions:

23 + 8662517 = 8662540
53 + 8662487 = 8662540
59 + 8662481 = 8662540
191 + 8662349 = 8662540
197 + 8662343 = 8662540
281 + 8662259 = 8662540
317 + 8662223 = 8662540
353 + 8662187 = 8662540

Showing the first eight; more decompositions exist.
