Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 958640, here are decompositions:

3 + 958637 = 958640
13 + 958627 = 958640
31 + 958609 = 958640
97 + 958543 = 958640
139 + 958501 = 958640
181 + 958459 = 958640
271 + 958369 = 958640
283 + 958357 = 958640

Showing the first eight; more decompositions exist.
