Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690540, here are decompositions:

127 + 8690413 = 8690540
163 + 8690377 = 8690540
181 + 8690359 = 8690540
223 + 8690317 = 8690540
337 + 8690203 = 8690540
349 + 8690191 = 8690540
367 + 8690173 = 8690540
421 + 8690119 = 8690540

Showing the first eight; more decompositions exist.
