Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707540, here are decompositions:

3 + 8707537 = 8707540
197 + 8707343 = 8707540
251 + 8707289 = 8707540
263 + 8707277 = 8707540
449 + 8707091 = 8707540
503 + 8707037 = 8707540
509 + 8707031 = 8707540
557 + 8706983 = 8707540

Showing the first eight; more decompositions exist.
