Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986540, here are decompositions:

7 + 986533 = 986540
31 + 986509 = 986540
43 + 986497 = 986540
103 + 986437 = 986540
283 + 986257 = 986540
349 + 986191 = 986540
397 + 986143 = 986540
409 + 986131 = 986540

Showing the first eight; more decompositions exist.
