Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040660, here are decompositions:

3 + 1040657 = 1040660
31 + 1040629 = 1040660
79 + 1040581 = 1040660
97 + 1040563 = 1040660
139 + 1040521 = 1040660
157 + 1040503 = 1040660
211 + 1040449 = 1040660
241 + 1040419 = 1040660

Showing the first eight; more decompositions exist.
